[XFS] merge xfs_imap into xfs_dilocate
xfs_imap is the only caller of xfs_dilocate and doesn't add any significant
value. Merge the two functions and document the various cases we have for
inode cluster lookup in the new xfs_imap.
Also remove the unused im_agblkno and im_ioffset fields from struct xfs_imap
while we're at it.
