driver core: Fix test_async_probe_init saves device in wrong array
[ Upstream commit 9be182da0a7526f1b9a3777a336f83baa2e64d23 ]
In test_async_probe_init, second set of asynchronous devices are saved
in sync_dev[sync_id], which should be async_dev[async_id].
This makes these devices not unregistered when exit.
> modprobe test_async_driver_probe && \
> modprobe -r test_async_driver_probe && \
> modprobe test_async_driver_probe
...
> sysfs: cannot create duplicate filename '/devices/platform/test_async_driver.4'
> kobject_add_internal failed for test_async_driver.4 with -EEXIST,
don't try to register things with the same name in the same directory.
