ipv6: ip6_sk_dst_check() must not assume ipv6 dst
It's possible to use AF_INET6 sockets and to connect to an IPv4
destination. After this, socket dst cache is a pointer to a rtable,
not rt6_info.
ip6_sk_dst_check() should check the socket dst cache is IPv6, or else
various corruptions/crashes can happen.
Dave Jones can reproduce immediate crash with
trinity -q -l off -n -c sendmsg -c connect
