There's no need to do header check for virtio-net since:
- Host sets dodgy for all gso packets from guest and check the header.
- Host should be prepared for all kinds of evil packets from guest, since
malicious guest can send any kinds of packet.
So this patch sets NETIF_F_GSO_ROBUST for virtio-net to skip the check.
