ipv6: set skb->protocol on tcp, raw and ip6_append_data genereated skbs
Currently we don't initialize skb->protocol when transmitting data via tcp, raw(with and without inclhdr) or udp+ufo or appending data directly to the socket transmit queue (via ip6_append_data). This needs to be done so that we can get the correct mtu in the xfrm layer. Setting of skb->protocol happens only in functions where we also have a transmitting socket and a new skb, so we don't overwrite old values.
