drm/i915/guc: Flush G2H handler during a GT reset

Browse source

Now that the error capture is fully decoupled from fence signalling
(request retirement to free memory, which in turn depends on resets) we
can safely flush the G2H handler during a GT reset. This eliminates
corner cases where GuC generated G2H (e.g. engine resets) race with a GT
reset.
