[IPSEC]: Use the correct family for input state lookup
When merging the input paths of IPsec I accidentally left a hard-coded
AF_INET for the state lookup call. This broke IPv6 obviously. This
patch fixes by getting the input callers to specify the family through
skb->cb.
Credit goes to Kazunori Miyazawa for diagnosing this and providing an
initial patch.
