KASAN caught some badness while running piglit with this applied, see
the attached dmesg excerpts.


At least some of this might be pre-existing bugs being exposed by this
change. E.g. I've been chasing another use-after-free, with
ttm_bo_delayed_delete trying to reserve a BO which has already been
destroyed. Looks like maybe the ddestroy list handling isn't quite
watertight yet.
