vhost_net: use XDP helpers
Make use of the xdp_{init,prepare}_buff() helpers instead of an open-coded version. Also, the field xdp->rxq was never set, so pass NULL to xdp_init_buff() to clear it. Signed-off-by: Matteo Croce <mcroce@microsoft.com> Signed-off-by: David S. Miller <davem@davemloft.net>
