Live Merge: Suspend disk stats collection during pivot

When pivoting to the new volume after an active layer merge, there is a
brief period where the vdsm metadata is out of sync.  During this time,
the disk stats collection thread will raise an exception since the drive
cannot be referred to by its old path.  Therefore we disable stats
collection during this short window until the metadata can be
synchronized.
