IPv6 needs a cookie in dst_check() call.
We need to add rx_dst_cookie and provide a family independent
sk_rx_dst_set(sk, skb) method to properly support IPv6 TCP early demux.

Applied, thanks.

Note: we could group sk_rx_dst/rx_dst_ifindex/rx_dst_cookie
in same cache line (in sk)
I don't think this is necessary, for now.
