This is not quite right. If no guc loading then there should be no guc_submission can't have submission without loading.
But, I guess that should be handled later.

And module parameters are integers and not booleans so compiler will not normalize the value for us. Quick and easy fix for the GuC loading code and the whole area can be evaluated afterwards.
