onSubsystemRestart should be triggered by wifi HAL when subsystem restart happened. Add log to debug why this callback function was not trigger at unexpected corner case. Bug: 201330066 Test: Manual test Change-Id: I160adc6006d078fcc72c1768927e87e378fd675e Merged-In: I160adc6006d078fcc72c1768927e87e378fd675e
