drm/sched: Fix clang build warning in kunit tests

Initializing compile time constant struct or arrays from another such
variable is a gcc extension, while clang strictly requires a compile time
constant literal.

As reported by LKP:

>> drivers/gpu/drm/scheduler/tests/tests_scheduler.c:675:10: error: initializer element is not a compile-time constant
                                 drm_sched_scheduler_two_clients_attr),
                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   include/kunit/test.h:224:13: note: expanded from macro 'KUNIT_CASE_PARAM_ATTR'
                     .attr = attributes, .module_name = KBUILD_MODNAME}
                             ^~~~~~~~~~

   672	static struct kunit_case drm_sched_scheduler_two_clients_tests[] = {
   673		KUNIT_CASE_PARAM_ATTR(drm_sched_scheduler_two_clients_test,
   674				      drm_sched_scheduler_two_clients_gen_params,
 > 675				      drm_sched_scheduler_two_clients_attr),
   676		{}
   677	};
   678

Fix it by using a compound literal as other tests do.
