Subject: [PATCH net 3/3] netfilter: nf_conntrack: fix rt6i_gateway checks for H.323 helper

Now when rt6_nexthop() can return nexthop address we can use it
for proper nexthop comparison of directly connected destinations.
For more information refer to commit bbb5823cf742a7
("netfilter: nf_conntrack: fix rt_gateway checks for H.323 helper").
