[IPV6]: Introduce the INET6_TW_MATCH macro.
We have INET_MATCH, INET_TW_MATCH and INET6_MATCH to test sockets and twbuckets for matching, but ipv6 twbuckets are tested manually. Here's the INET6_TW_MATCH to help with it. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
