virtio_net: xsk: tx: support xmit xsk buffer

Browse source

The driver's tx napi is very important for XSK. It is responsible for
obtaining data from the XSK queue and sending it out.

At the beginning, we need to trigger tx napi.

virtnet_free_old_xmit distinguishes three type ptr(skb, xdp frame, xsk
buffer) by the last bits of the pointer.
