gsm_04_08.c: Kill duplication pointed out by Andreas Eversberg

Introduce the internal gsm0408_authorize that will determine
if we allow the user into our network. If allowed a new tmsi
will be allocated, the subscr_update will be called, the loc_operation
released, and the accept sent. Otherwise just return 0.

The code was copied from mm_rx_id_resp.
