dm raid1: fix to commit pending clear region requests
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.
