This allows destruction of bo backed memory without a reservation. It's required for being able to rework the delayed destroy path, as it is no longer guaranteed to hold a reservation before unlocking. However any previous wait is still guaranteed to complete, and it's one of the last things to be done before the buffer object is freed.
