Fix: Handle CM service request on already secured channel correctly
A CM service request must be acknowledged also, when encryption is already
enabled.
Without encryption enabled, the security status is GSM_SECURITY_NOTAVAIL,
which causes a CM service acknowledge. On initial CM service request, the
security status is GSM_SECURITY_SUCCEED, if encryption is enabled. This
will not lead to an acknowledge, because the cyphering command implies an
acknowlege. An additional CM service request requires an acknowledge, so
I added a new security status: GSM_SECURITY_ALREADY
