Subject: drm/i915: Use bound list for inactive shrink
Do to the move active/inactive lists, it no longer makes sense to use
them for shrinking, since shrinking isn't VM specific (such a need may
also exist, but doesn't yet).
What we can do instead is use the global bound list to find all objects
which aren't active.
