gtphub: don't always try to do GGSN resolution.

If a GGSN is already known from unmapping, don't invoke a host resolution.
In a live working environment, it wouldn't hurt, because the lookups would
mostly return from the cache. But in a testing environment without a name
server, it barfs on every packet.
