When resetting ctrlr, adminq is disconnected first. If adminq is disconnected,
admin passthrough request is rejected with -ENXIO.
But resetting ctrlr may succeed. If resetting ctrlr succeeds, adminq is
connected again, and admin passthrough request will be
submitted successfully.
On the other hand, if ctrlr is failed, admin passthrough request is
rejected with -ENXIO. But when resetting ctrlr, ctrlr is set to unfailed.
Hence bdev_nvme_admin_passthru() skips any ctrlr which is resetting
or failed, and calls bdev_nvme_admin_passthru_complete() with -ENXIO
if no available ctrlr is found.
bdev_nvme_admin_passthru_complete() queues admin passthrough request
and retry it one second later if ctrlr is resetting.
