I don't think this will work. The other scenario is the original admin command
was fine. We enter nvme_update_formats, grab the semaphore as write, issue the
nvme admin identify, that fails, we enter timeout, and attempt to down_read in
diasble_dev -> stop queues and get stuck there.
We need a way where we are not holding a down_write on the semaphore while issuing
I/O.
