virtio-balloon: Rip out qemu_balloon_inhibit()
The only remaining special case is postcopy. It cannot handle concurrent discards yet, which would result in requesting already sent pages from the source. Special-case it in virtio-balloon instead. Introduce migration_in_incoming_postcopy(), to find out if incoming postcopy is active. Reviewed-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Reviewed-by: Michael S.
