Let's properly adjust BALLOON_MIGRATE like the other drivers.

Note that the INFLATE/DEFLATE events are triggered from the core when enqueueing/dequeueing pages.

Not completely sure whether really is stable material, but the fix is trivial so let's just CC stable.

This was found by code inspection.
