CC: fix sanity expectations for call establishment
Recent 'add full SDP codec information to the MNCC...' patch has added a strict
CC state sanity check, which is too strict:
In tests with 200 concurrent calls, situations came up where the MNCC is faster
than the Abis in establishing a call. If that happens, the CC state machine is
already in GSM_CSTATE_ACTIVE when the RR channel assignment completes.
Also allow GSM_CSTATE_ACTIVE state for accepting an Assignment Complete.
