virtio-balloon: Unregister savevm section on device unplug
Migrating after unplugging a virtio-balloon device resulted in an error
message on the destination:
Unknown savevm section or instance '0000:00:04.0/virtio-balloon' 0
load of migration failed
Fix this by unregistering the section on device unplug.
