In particular, in icc_sync_state() when a node with initial BW has zero requests. Since BCMs aren't added to the commit list in these cases, we don't actually send the zero BW request to HW. So the resources remain on unnecessarily. Add BCMs to the commit list in pre_aggregate() instead, which is always called even when there are no requests.
