virtio-net: support queue_enable
Support queue_enable in vhost-kernel scenario. It can be called when
a vq reset operation has been performed and the vq is restared.
It should be noted that we can restart the vq when the vhost has
already started. When launching a new vhost device, the vhost is not
started and all vqs are not initalized until VIRTIO_PCI_COMMON_STATUS
is written. Thus, we should use vhost_started to differentiate the
two cases: vq reset and device start.
Currently it only supports vhost-kernel.
