Don't route messages to an SGSN if it is down

If an SGSN in a pool is down we expect the messages to instead be sent
to a different SGSN in the pool. That SGSN will not necessarily know
what to do with those messages, but it should (implicitly) detach that
UE so that it can reattach at the new SGSN. Otherwise UEs on a failed
SGSN would simply stop working as the messages would never be forwarded
anywhere.
