Device removal sequence may have crashed because the controller (and admin queue space) was freed before we destroyed the admin queue resources. Thus we want to destroy the admin queue and only then queue controller deletion and wait for it to complete. More specifically we: 1. own the controller deletion (make sure we are not competing with another deletion). 2. get rid of inflight reconnects if exists (which also destroy and create queues). 3. destroy the queue. 4. safely queue controller deletion (and wait for it to complete).
