Commit 5b8f3c8d30a6 ("virtio_net: Add XDP related stats") tries to count TX XDP stats in virtnet_receive(). This will cause several issues: - virtnet_xdp_sq() was called without checking whether or not XDP is set. This may cause out of bound access when there's no enough txq for XDP. - Stats were updated even if there's no XDP/XDP_TX. Fixing this by reusing
