st/dri: invalidate_resource depth/stencil before flush_resource

This allows freedreno to be aware of the depth invalidate when flushing
batches on flush_resource.

AFAIK, the only other driver which might care about this change is vc4,
where I think it should help by allowing the depth invalidate to work with
GALLIUM_HUD.
