[TCP]: Fix zero port problem in IPv6
When we link a socket into the hash table, we need to make sure that we set the num/port fields so that it shows us with a non-zero port value in proc/netlink and on the wire. This code and comment is copied over from the IPv4 stack as is. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
