CEC: Fixes bugs in routing control

1) HdmiControlService#inInDeviceList was passed the parameters in
   a wrong order. Fixed here. Turned the method to private as well.
2) Passed path not port to Routing control when handling active
   path removal to update the active path correctly.
3) adb dumpsys hdmi_control outputs the status of the connected
   CEC devices for debugging.
