As pointed in other mail thred, trying to cover the following case:

1. oFono core is informed of the modem handled setup call and requests
user confirmation
2. User confirms the call
3. User confirmation sent to modem.
4. Due to some reason, modem is not able to setup the call. So, basically
oFono core is not notified of any call status notifications
5. Modem sends the terminal response to SAT and notifies oFono core of the
command/session completion

Basically, if the modem due to some reason fails to initiate/setup the
call and call status notifications not sent to the voice call driver side.
This case, we will be left with dial_req, message and icon id set but not
freed.

Regards,
Jeevaka
