memory: use conftest test for class_create

Browse Source 
In Linux v6.4, the module pointer argument is removed from the
class_create() function. Add a test to the conftest script that checks
if this argument for the class_create() function has been removed and
use the definition created by conftest to select which version of the
function is used.
