Shixiong Ou 28cc4d5a75 drm/sched: Create a fake device for KUnit tests
The DRM scheduler KUnit tests pass NULL for the dev field in
drm_sched_init_args, which NULL-pointer dereferences in the drm_sched_job
trace event via dev_name() on sched->dev.

Give the mock scheduler a device with kunit_device_register(), which is
also cleaned up at test exit. A per-function counter keeps the device
names unique, since some tests create several mock schedulers.
