Not a whole bool? I think it could be.

Pretty sure rather listing three three function calls here would be
nicer;
i915_ppgtt_do_close(vm->active_list);
i915_ppgtt_do_close(vm->inactive_list);

Patch really makes the tracking easier to follow, there also seems to
be a hint of paranoia, but it's with GEM_BUG_ON() so should not hurt.
