Since the introduction of multifd, it's possible to perform a multifd migration and finish it using postcopy.
A bug introduced by yank (fixed on cfc3bcf373) was previously preventing a successful use of this migration scenario, and now it should be working on most cases. But since there is not enough testing/support nor any reported users for this scenario, we should disable this combination before it may cause any problems for users.
