Chris Wilson e1c0c91bda drm/i915: Wake up all waiters before idling 
When we idle, we wakeup the first waiter (checking to see if it missed
an earlier wakeup) and disarm the breadcrumbs. However, we now assert
that there are no waiter when the interrupt is disabled, triggering an
assert if there were multiple waiters when we idled.
