gpu: nvgpu: initialize boolean to prevent UBScan bugs

Browse Source 
UBSan flags the error "load of value 255 is not a valid value for
type '_Bool'". This is caused due to unitialized boolean value as given
in the UBSan specification i.e. the following check
-fsanitize=bool: Load of a bool value which is neither true nor
false.
