    drm/i915: Always retire residual requests before suspend

    If the driver is wedged, we skip idling the GPU. However, we may still
    have a few requests still not retired following the wedging (since they
    will be waiting for a background worker trying to acquire struct_mutex).
    As we hold the struct_mutex, always do a quick request retirement in
    order to flush the wedged path.
