This fixes segfaults on reads (implicit reads on writes too), ouch.
Thanks to The Raven for reporting the problem and testing my patch, and
to Alexander Irenkov for providing a workable fix for it additionally.

There were actually two problems:
1) The loop conditions were bogus which could lead to read errors
   (e.g. on implicit erase verifications).
2) The offset used within the read buffers provided to spi_nbyte_read()
   and memcpy() were not starting at 0 but the offset of the block
   within the flash chip (which has nothing to do with read buffer in
   most cases).

This patch works similarly to Alexander's but is intended to be
more readable.

It is very similar to LE25FW418A, except for HD_READ support (that
is not implemented in flashrom anyway yet) and allowed voltage range.

Probing, erasing, reading and writing has been tested.

This chip is found on Seagate Constellation hard drives.

We are more verbose inside erase_and_write_flash() although it does not
matter as much as at the end of the whole process in doit().

New output for the non-fatal (i.e. read-protected + successful recovery read) case:

Reading old flash chip contents... done.
Erasing and writing flash chip... spi_block_erase_d8 failed during command execution at address 0x8000
Reading current flash chip contents... done. spi_chip_erase_c7 failed during command execution
FAILED!
Uh oh. Erase/write failed. Checking if anything has changed.
Reading current flash chip contents... done.
Good, writing to the flash chip apparently didn't do anything.
Please check the connections (especially those to write protection pins) between
the programmer and the flash chip. If you think the error is caused by flashrom
please report this on IRC at chat.freenode.net (channel #flashrom) or
mail flashrom@flashrom.org, thanks!

Because the programmer initialization that has to be called way
earlier and independently elsewhere, it does not make a lot of sense
to deinit within doit(). Also, free the logfile name at the end of
main() to catch more execution paths and because this moves it to
the other cleanup instructions.

Previously the external DMI decoder did not allow this to happen because
all possible pointers were initialized at startup by the output of
'dmidecode -s ...' which has default values for all supported types.

The now active internal DMI decoder does work differently: it scans the
complete DMI table once and copies the available strings. Therefore, strings
that are not set by the firmware are left at their default value of NULL.

A segfault would arise if the following conditions are all true:
 - the firmware sets up a DMI/SMBIOS table which has at least a correct
   checksum, and
 - that table does *not* define at least one of the DMI strings we use
   for matching (as defined by dmi_strings[] in dmi.c), and
 - there exists a board enable whose PCI IDs are matched by the board,
   and which has a DMI string set that ends with a $ anchor, and
 - the user calls the internal programmer of flashrom without the
   optional mainboard parameter.

This was first observed by Gelip on an abit BF6 using the coreboot port
for the abit BE6-II V2.0.
The segfault was reproduced by Idwer Vollering on an ASUS F2A85-M with
the default DMI values of CONFIG_MAINBOARD_SMBIOS_MANUFACTURER etc.
overwritten and a forged board enable matching his board.
Idwer also verified that this patch fixes the problem, thanks a lot!
