This removes two redundancies:
1) The test (skb->protocol == htons(ETH_P_IPV6) in tcp_v6_init_sequence()
is always true, due to
* tcp_v6_conn_request() is the only function calling this one
* tcp_v6_conn_request() redirects all skb's with ETH_P_IP protocol to
tcp_v4_conn_request() [ cf. top of tcp_v6_conn_request()]
2) The first argument, `struct sock *sk' of tcp_v{4,6}_init_sequence() is
never used.
