Subject: [PATCH] Stop setting route pointing back to tenant router

This removes the logic to add a route pointing to the IPv4
tenant private network range since the router is performing
SNAT. If reaching the IPs via the route worked at all, it was
by accident since this behavior is certainly not guaranteed
by Neutron.
