The delayed_slow_work code was replace with a more generic work queue,
with a subtle different API. This difference being that the new
queue_delayed_work() return 0 if the work is already on the queue,
non-zero otherwise. The DRM_ERROR() are now wrong (printed after a
successful insertion) and indeed superfluous so remove them.
