Subject: [PATCH] drm/i915: Objects on the unbound list may still have an
 active reference

Due to the lazy retirement semantics, even though we have unbound an
object, it may still hold onto an active reference. So in the debug code,
play safe.

v2: Export i915_gem_shrink() rather than opencoding it.
