debugobjects: Refill per CPU pool more agressively
Right now the per CPU pools are only refilled when they become
empty. That's suboptimal especially when there are still non-freed objects
in the to free list.
Check whether an allocation from the per CPU pool emptied a batch and try
to allocate from the free pool if that still has objects available.
