From: Darrick J. Wong <djwong@xxxxxxxxxx>
All existing btree types set XFS_BTREE_CRC_BLOCKS when running against a
V5 filesystem. All currently proposed btree types are V5 only and use
the richer XFS_BTREE_CRC_BLOCKS format. Therefore, we can drop this
flag and change the conditional to xfs_has_crc.
