[PATCH] qemu: forbid a few unsupported things for vhost-user/passt interfaces

passt in vhost-user mode doesn't support using multiple queues. The path of the socket is auto-generated by libvirt for vhost-user/passt; it can't be set by the user The passt end of a vhost-user socket is always the server, and the qemu end is always a client.
