Set bo->resv to ttm_resv during BO cleanup. This way freed BOs can be
better reaped during eviction.

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.

I guess this because you move the resv changing out of lock of bo->resv.
Because at the beginning ttm_mem_evict_first may __ttm_bo_reserve(bo->resv) success, and then bo->resv has been changed by another thread. That is not matched and at this point bo->ttm_resv also may been freed already.
And I think it is not easy to put it out of two lock of bo->resv and bo->ttm_resv.
Thanks

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.
