call: Fix call release handling on mncc connection loss

The app_mncc_disconnected will be called when the MNCC socket is down
and lead to all calls being released. It directly released the call but
did not stop the MNCC CMD timer. Go through the call release callback.

This lead to the timer not being removed:
