driver core: Fix test_async_driver_probe if NUMA is disabled

Browse source

commit 264d25275a upstream.

Since commit 57ea974fb8 ("driver core: Rewrite test_async_driver_probe
to cover serialization and NUMA affinity"), running the test with NUMA
disabled results in warning messages similar to the following.

test_async_driver test_async_driver.12: NUMA node mismatch -1 != 0

If CONFIG_NUMA=n, dev_to_node(dev) returns -1, and numa_node_id()
returns 0. Both are widely used, so it appears risky to change return
values. Augment the check with IS_ENABLED(CONFIG_NUMA) instead
to fix the problem.
