af_packet: Use virtio_net_hdr_from_skb() directly.
Remove static function __packet_rcv_vnet(), which only called virtio_net_hdr_from_skb() and BUG()ged out if an error code was returned. Instead, call virtio_net_hdr_from_skb() from the former call sites of __packet_rcv_vnet() and actually use the error handling code that is already there.
