In resource_test_insert_resource(), the pointer is used in error message
after kfree(). This is user-after-free. To fix this, we need to call
kunit_add_action_or_reset() to schedule memory freeing after usage. But
kunit_add_action_or_reset() itself may fail and free the memory. So, its
return value should be checked and abort the test for failure. Then, we
found that other usage of kunit_add_action_or_reset() in
resource_test_region_intersects() needs to be fixed too. We fix all these
user-after-free bugs in this patch.
