layer23: IMSI detach works now.

Pressing CTRL+c causes the detach process to run, then the mobile exits.
This procedure only runs after attachment (location update) and if detach
is required.

The SABM with the detach message is confirmed by a DISC message. the BS11
says that this is caused by sequence error or N200+1 error. Maybe someone
can trace that.
