xfs: add a block to inode count converter
Add new helpers to convert units of fs blocks into inodes, and AG blocks
into AG inodes, respectively. Convert all the open-coded conversions
and XFS_OFFBNO_TO_AGINO(, , 0) calls to use them, as appropriate. The
OFFBNO_TO_AGINO macro is retained for xfs_repair.
