[SMS] Properly reject processing of compressed SMS

As we don't support compressed SMS, we have to properly reject it.

In the existing code, we segfaulted at some later point since the error
handling was incomplete.

This was triggered by some obscure STK SIM card that insisted on sending a
compressed SMS after registering to the OpenBSC network.
