Display is turned off by i915_drm_suspend() during the suspend procedure, removing the last reference of some gem objects that were used by display. The issue is that those objects are only actually freed when mm.free_work executed and that can happen very late in the suspend process causing issues. So here draining all freed objects released by display fixing suspend issues.
