mm: slub: test: Use the kunit_get_current_test() function
Use the newly-added function kunit_get_current_test() instead of accessing current->kunit_test directly. This function uses a static key to return more quickly when KUnit is enabled, but no tests are actively running. There should therefore be a negligible performance impact to enabling the slub KUnit tests. Other than the performance improvement, this should be a no-op.
