Sync vPool with reality does not remove discrepancies from ovsdb

[kinvaris]

We have some vdisks that are not anymore in the volumedriver. When trying a sync vpool with reality it does not remove the discrepancies from the ovsdb.

This ticket is obsolete as this functionality is removed with the vMachine cleanup. Nevertheless I found a small remaining piece of (not working) code related to that removed sync. I'll use this ticket to clean this up.

Fixed by #722

For QA: There should be nothing in the GUI, API or controllers to sync a vPool.
