While forcing the CPU to unrealize by hand does trigger the clean-up code we never fully free resources because refcount never reaches zero. This is because QOM automatically added objects without an explicit parent to /unattached/, incrementing the refcount.
Instead of manually triggering unrealization just unparent the object and let the device machinery deal with that for us.
