This fixes a crash where we assign tcp_prot to IPv6 sockets instead of tcpv6_prot. Previously we overwrote the sk->prot field with tcp_prot even in the AF_INET6 case. This patch ensures the correct tcp_prot and tcpv6_prot are used. Tested with 'netserver -6' and 'netperf -H [IPv6]' as well as 'netperf -H [IPv4]'. The ESTABLISHED check resolves the previously crashing case here.
