Random tests using GEM without GEM, eh?

Should be papered over with

    drm/i915: Wait for a moment before forcibly resetting the device

    During igt, we ask to reset the device if any requests are still
    outstanding at the end of a test, as this quickly kills off any
    erroneous hanging request streams that may escape a test. However, since
    it may take the device a few milliseconds to flush itself after the end
    of a normal test, *cough* guc *cough*, we may accidentally tell the
    device to reset itself after it idles. If we wait a moment, our usual
    I915_IDLE_ENGINES_TIMEOUT of 200ms (seems a bit high, but still better
    than umpteen hangchecks!), we can differentiate better between a stuck
    engine and a healthy one, and so avoid prematurely forcing the reset and
    any extra complications that may entail.
