Julian Anastasov bbb5823cf7 netfilter: nf_conntrack: fix rt_gateway checks for H.323 helper 
After the change "Adjust semantics of rt->rt_gateway"
(commit f8126f1d51) we should properly match the nexthop when
destinations are directly connected because rt_gateway can be 0.

The rt_gateway checks in H.323 helper try to avoid the creation
of an unnecessary expectation in this call-forwarding case:

http://people.netfilter.org/zhaojingmin/h323_conntrack_nat_helper/#_Toc133598073

However, the existing code fails to avoid that in many cases,
see this thread:

http://marc.info/?l=linux-netdev&m=135043175028620&w=2

It seems it is not trivial to know from the kernel if two hosts
have to go through the firewall to communicate each other, which
is the main point of the call-forwarding filter code to avoid
creating unnecessary expectations.

So this patch just gets things the way they were as before
commit f8126f1d51.
