dataplane: sync virtio.c and vring.c virtqueue state
Load the virtio.c state into vring.c when we start dataplane mode and vice versa when stopping dataplane mode. This patch makes it possible to start and stop dataplane any time while the guest is running. This will eventually allow us to go back to QEMU main loop for bdrv_drain_all() and live migration. In the meantime, this patch makes the dataplane lifecycle more robust but should make no visible difference. It may be useful in the virtio-net dataplane effort.
