virtio-net: re enable XDP_REDIRECT for mergeable buffer
XDP_REDIRECT support for mergeable buffer was removed since commit 7324f539 ("virtio_net: disable XDP_REDIRECT in receive_mergeable() case"). This is because we don't reserve enough tailroom for struct skb_shared_info which breaks XDP assumption. So this patch fixes this by reserving enough tailroom and using fixed size of rx buffer.
