virtio-net: support queue reset
virtio-net and vhost-kernel implement queue reset. Queued packets in the corresponding queue pair are flushed or purged. For virtio-net, userspace datapath will be disabled later in __virtio_queue_reset(). It will set addr of vring to 0 and idx to 0. Thus, virtio_net_receive() and virtio_net_flush_tx() will not receive or send packets. For vhost-net, the datapath will be disabled in vhost_net_virtqueue_reset().
