When we're effectively deflating the balloon while migrating a page

Let's do that. This is a preparation for factoring out this handling to
the core code, making it work in a similar way first.

As this (deflating while migrating because of inflation error) is a
corner case that I don't really expect to happen in practice
and the stats are not that crucial, this likely doesn't classify as a fix.
