With the code as it is, it is possible for oustanding clear region
requests never to get flushed when a mirror is deactivated or suspended.
This means there will always be some resync work required when a mirror
is activated, even though it may very well be in-sync.
Always requesting the flush doesn't hurt us. This is because the log
tracks whether any changes occurred and, if not, no flush is performed.
