bsc: Fix crash that can occur on RF Failure

When we got a clear request we did not clear the internal
association between the gsm_subscriber_connection and the SCCP
part. When we got a DTAP message before the CLEAR COMMAND we
will end up in a crash as the ->bts pointer of the connection
has been cleared.
