xfs: explicitly pass buffer size to xfs_corruption_error
Explicitly pass the buffer length to xfs_corruption_error() instead of assuming XFS_CORRUPTION_DUMP_LEN so that we avoid dumping off the end of the buffer. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Dave Chinner <dchinner@redhat.com>
