xfs: move xfs_rmap_update_defer_add to xfs_rmap_item.c

Source kernel commit: ea7b0820d960d5a3ee72bc67cbd8b5d47c67aa4c

Move the code that adds the incore xfs_rmap_update_item deferred work
data to a transaction to live with the RUI log item code.  This means
that the rmap code no longer has to know about the inner workings of the
RUI log items.

As a consequence, we can get rid of the _{get,put}_group helpers.
