In commit 9192d4fb811e ("drm/i915/guc: Extract doorbell creation
from client allocation") we introduced asymmetry in doorbell cleanup
to avoid warnings due to failed communication with already reset GuC.
As we improved our reset/unload paths, we can restore symmetry in
doorbell cleanup, as GuC should be still active by now.
