Ok is a reword enough? In that case I'll resend.

I moved all the destruction to happen when release_list refcount drops to 0.
This removes the special handling of ttm_bo_cleanup_memtype_use, and
makes it part of the normal bo destruction instead.

It also meant that move_notify and unbind/destroy was without reservation, simply
because it was done during normal destruction instead. At that point you may no longer
hold a reservation, but you can already be sure you're the only one touching it.

It is optional and I can drop this patch if the behavior change is unwanted.
