[PATCH 9/9] xfs: move xfs_refcount_update_defer_add to xfs_refcount_item.c

["Darrick J. Wong" <djwong@xxxxxxxxxx>]

From: Darrick J. Wong <djwong@xxxxxxxxxx>

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

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