virtio_net: setup xdp_rxq_info
The virtio_net driver doesn't dynamically change the RX-ring queue
layout and backing pages, but instead reject XDP setup if all the
conditions for XDP is not meet. Thus, the xdp_rxq_info also remains
fairly static. This allow us to simply add the reg/unreg to
net_device open/close functions.
Driver hook points for xdp_rxq_info:
* reg : virtnet_open
* unreg: virtnet_close
V3:
- bugfix, also setup xdp.rxq in receive_mergeable()
- Tested bpf-sample prog inside guest on a virtio_net device
