The typical pattern of these lookups are -Lookup -Put on validate list if not already there. -Unreference And since we are the exclusive user of the context during lookup time, we can be sure that the resource will stay alive during the sequence. So avoid taking a reference during lookup, and also avoid unreferencing when done. There are two users outside of command buffer validation and those are refcounted explicitly.
