The issue is clear now. But this patch just puts the situation before below fix:
"it doesn't create the actual datagram socket until you call .dev_start()."
No, if the queue exist, the datagram socket still get created in vhost_create
API, since the vhost_driver_register still exist in vhost_create.
The queue can never be created, as it's still not probed.
