    drm/i915: Stop engines when declaring the machine wedged

so time to accept the failure and turn off the DRM_ERROR.

    drm/i915: Silence debugging DRM_ERROR for failing to suspend vlv powerwells
    
    If we try to suspend a wedged device following a GPU reset failure, we
    will also fail to turn off the rc6 powerwells (on vlv), leading to a
    *ERROR*. This is quite expected in this case, so the best we can do is
    shake our heads and reduce the *ERROR* to a debug so CI stops
    complaining.

This has not stopped happening. Here are the latest failures:

But that kernel was from before the fix was applied.

Not being seen after these failures, you were right! Thanks and sorry!
