hw/virtio: move vhd->started check into helper and add FIXME
The `started` field is manipulated internally within the vhost code except for one place, vhost-user-blk via f5b22d06fb (vhost: recheck dev state in the vhost_migration_log routine). Mark that as a FIXME because it introduces a potential race. I think the referenced fix should be tracking its state locally.
