Introduce vhost_virtqueue_reset(), which can reset the specific virtqueue in the device. Then it will unmap vrings and the desc of the virtqueue. Here we do not reuse the vhost_net_stop_one() or vhost_dev_stop(), because they work at queue pair level. We do not use vhost_virtqueue_stop() because it may stop the device in the backend. This patch only considers the case of vhost-kernel, when NetClientDriver is NET_CLIENT_DRIVER_TAP. Furthermore, we do not need net->nc->info->poll() because it enables userspace datapath and we want to stop all datapaths for this reset virtqueue here.
