msm: cpp: Ignore input validation for sof freeze/unfreeze command ids

Browse source 
The command ids do not have separate pointer payload and would
return error. If error is returned without waiting for any
subsequent driver operation like a timeout handling to complete,
it would result in synchronization issues and potential crashes.
Ignore input validation for sof freeze/unfreeze command ids.
