PATCH3 refactors the VFIO migration blocker related code based on suggestions from Joao and Cedric, so that code is simpler and "Migration disabled" printed in right case.

Thanks v3: Add PATCH1,2 to fix hotplug bug Fix bugs in PATCH3 Avihai and Joao pointed out Tested vfio hotplug/unplug with vfio migration supported and unsupported cases, including blocker adding failed case.
