Bluetooth: Killing the process in case of stop_timeout

While stopping the profiles, if stop timeout comes,
it will move back to BLE_ON states and from there it
moves to BLE_OFF state if there is no BLE app open.
This will trigger the stack shutdown while some
profiles may still be active.  We can not move to
OFF state or BLE_ON state. The only choice is to
restart the process.
