xfs_btree_init_block_int() can determine whether crcs are in effect without the passed-in XFS_BTREE_CRC_BLOCKS flag; the mp argument allows us to determine this from the superblock. Remove the flag from callers, and use xfs_sb_version_hascrc(&mp->m_sb) internally instead. This removes one difference between the if & else cases in the callers.
