HDMI: Delay OTP in case standby process started

If there was a standby request right after wake up started, OneTouchPlay
would've started before the local device had the chance to disable the
action. The result was the device waking up instead of going to sleep.
This is an edge case, but the CTS mentioned below wouldn't pass without
this CL.

Test: run cts -m CtsHdmiCecHostTestCases -t android.hdmicec.cts.common.HdmiCecPowerStatusTest#cect_hf4_6_22_interruptedPowerOn
