[PATCH 2/2] nvme-rdma: move admin queue cleanup to nvme_rdma_free_ctrl

[Sagi Grimberg]

> This patch introduces asymmetry between create and destroy
> of the admin queue. Does this alternative patch solve
> the problem?
>
> The patch changes the order of device removal flow from:
> 1. delete controller
> 2. destroy queue
>
> to:
> 1. destroy queue
> 2. delete controller
>
> Or more specifically:
> 1. own the controller deletion (make sure we are not
> competing with anyone)
> 2. get rid of inflight reconnects (which also destroy and
> create queues)
> 3. destroy the queue
> 4. safely queue controller deletion
>
> Thoughts?

Should mention that patch 1 is not needed as well with this...
