    drm/i915: Stop spinning for DROP_IDLE (debugfs/i915_drop_caches)

    If the user is racing a call to debugfs/i915_drop_caches with ongoing
    submission from another thread/process, we may never end up idling the
    GPU and be uninterruptibly spinning in debugfs/i915_drop_caches trying
    to catch an idle moment.

    Just flush the work once, that should be enough to park the system under
    correct conditions. Outside of those we either have a driver bug or the
    user is racing themselves. Sadly, because the user may be provoking the
    unwanted situation we can't put a warn here to attract attention to a
    probable bug.
