driver core: test_async: fix an error code
[ Upstream commit 22d2381bbd70a5853c2ee77522f4965139672db9 ]
The test_platform_device_register_node() function should return error
pointers instead of NULL. That is what the callers are expecting.
Fixes: 57ea974fb871 ("driver core: Rewrite test_async_driver_probe to cover serialization and NUMA affinity")
