[PATCH net] virtio-net: add missing virtqueue kick when flushing packets

We tends to batch submitting packets during XDP_TX. This requires to kick virtqueue after a batch, we tried to do it through xdp_do_flush_map() which only makes sense for devmap not XDP_TX. So explicitly kick the virtqueue in this case. Reported-by: Kimitoshi Takahashi
