[PATCH] xfs_db: make write/fuzz -c and -d work on non-crc filesystems

["Darrick J. Wong" <darrick.wong@oracle.com>]

For a non-crc filesystem, make write/fuzz -c and -d work properly
instead of bailing out.  Since there's no checksum to update, both
cases collapse to setting the field value without calling the write
verifier.
