xfs: provide helper for counting extents from if_bytes
commit 5d829300bee000980a09ac2ccb761cb25867b67c upstream.
The open-coded pattern:
ifp->if_bytes / (uint)sizeof(xfs_bmbt_rec_t)
is all over the xfs code; provide a new helper
xfs_iext_count(ifp) to count the number of inline extents
in an inode fork.
[dchinner: pick up several missed conversions]
