Call setArcStatus(false) before standby

[Description]
DisableDevice is called before standby.
If clearDeviceInfoList() is called before <Terminate ARC> is received,
CEC can't get device info & portId of AVR
And thus enableAudioReturnChannel is not success.

Therefore, we call setArcStatus(false) earlier
before RequestArcTerminationAction and receives <Terminate ARC>

Note that we don't use SetArcTransmissionStateAction since it is not
safe to create too many Actions during standby process
