ASoC: SOF: ipc4-topology: Allow bytes controls without initial payload 
It is unexpected, but allowed to have no initial payload for a bytes
control and the code is prepared to handle this case, but the size check
missed this corner case.

Update the check for minimal size to allow the initial size to be 0.
