Subject: [PATCH] [XFS] Fix realtime subvolume expansion, a porting bug b0rked
 it.  Coverity made me look at this code (bug id #344). We only return with
 XFS_ERROR(EINVAL) if mp->m_rtdev_targp is valid and pass it otherwise to
 xfs_read_buf() where some function calls later it gets dereferenced by an
 assert.
