gbproxy: Discard UL PTP messages with an unknown BVCI

Currently all PTP messages are in general forwarded to the SGSN even
when the BVCI is not known to the gbproxy. Only if message patching
is active and the peer cannot be determined, a log message is
generated, a STATUS message returned, and the message discarded.
The intention for this was to keep the old gbproxy's behaviour if
patching is disabled. But the code gets much more complex this way.
Another drawback is that when the SGSN returns a corresponding STATUS
message, it cannot be routed to the BSS where the original message
came from.

This patch therefore changes the behaviour to reject BSSGP PTP uplink
messages immediately if the BVCI is not known.
