drm/i915: Drain freed object after suspend display

Browse source

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.
