Change the left/right variables to the proper always 64bit xfs_dfsbo_t
type because otherwise compilation fails for Geert on m68k without
CONFIG_LBD:

| fs/xfs/xfs_btree.c: In function 'xfs_btree_readahead_lblock':
| fs/xfs/xfs_btree.c:736: warning: comparison is always true due to limited range of data type
| fs/xfs/xfs_btree.c:741: warning: comparison is always true due to limited range of data type
