Shuhei Matsumoto aca0d56e3d bdev/nvme: Reconnect ctrlr after it is disconnected at completion poller
spdk_nvme_ctrlr_disconnect() will be made asynchronous in the
following patches and so we will need to have some changes.

spdk_nvme_ctrlr_disconnect() disconnects adminq and ctrlr synchronously
now.

If spdk_nvme_ctrlr_disconnect() is made asynchronous,
spdk_nvme_ctrlr_process_admin_completions() will complete to disconnect
adminq and ctrlr, and will return -ENXIO only if adminq is disconnected.

However even now spdk_nvme_ctrlr_process_admin_completions() returns
-ENXIO if adminq is disconnected.

So as a preparation, set a callback before calling spdk_nvme_ctrlr_disconnect()
and call the callback if it is set and spdk_nvme_ctrlr_process_admin_completions()
returns -ENXIO.

Besides, fix the return value of bdev_nvme_poll_adminq() in this patch.
