xfs: more do_div cleanups
On some architectures do_div does the pointer compare trick to make sure that we've sent it an unsigned 64-bit number. (Why unsigned? I don't know.) Fix up the few places that squawk about this; in xfs_bmap_wants_extents() we just used a bare int64_t so change that to unsigned. In xfs_adjust_extent_unmap_boundaries() all we wanted was the mod, and we have an xfs-specific function to handle that w/o side effects, which includes proper casting for do_div. In xfs_daddr_to_ag[b]no, we were using the wrong type anyway; XFS_BB_TO_FSBT returns a block in the filesystem, so use xfs_rfsblock_t not xfs_daddr_t, and gain the unsignedness from that type as a bonus.
