[PATCH] driver core: test_async: fix an error code

[Dan Carpenter]

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")
