[PATCH 09/44] xfs: support recovering refcount intent items targetting realtime extents

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

From: Darrick J. Wong <djwong@xxxxxxxxxx>

Now that we have reflink on the realtime device, refcount intent items
have to support remapping extents on the realtime volume.
