From: Darrick J. Wong <djwong@xxxxxxxxxx>
Move the code that adds the incore xfs_rmap_update_item deferred work
data to a transaction 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.
