[IPV6]: Mischecked tw match in __inet6_check_established.
When looking for a conflicting connection the !sk->sk_bound_dev_if
check is performed only for live sockets, but not for timewait-ed.
This is not the case for ipv4, for __inet6_lookup_established in
both ipv4 and ipv6 and for other places that check for tw-s.
Was this missed accidentally? If so, then this patch fixes it and
besides makes use if the dif variable declared in the function.
