scripts: conftest: Fix test for __alloc_disk_node

Browse Source 
The test to see if the function __alloc_disk_node() has the 'lkclass'
argument is not working as expected and so builds for Linux v5.18 and
Linux v5.19 are failing. The problem is that the type 'NULL' is not
defined and so the test always fails. Fix this by using the
'lock_class_key' type and including the appropriate headers.
