After a controller was hot-removed, if a reset sequence started to
the controller, spdk_nvme_ctrlr_disconnect() failed and caused core
dump in debug mode.
When implemented, how to cause the failure and how to process the
failure were not clear. Hence assert was added to detect the
failure.
We know how we cause the failure now. Let's handle the failure
appropriately.
If spdk_nvme_ctrlr_disconnect() fails, we are on the nvme_ctrlr->thread.
Hence call bdev_nvme_reset_complete() with failure immediately.
Even if spdk_nvme_ctrlr_disconnect() completes synchronously, the
completion callback is executed asynchronously when polling an adminq.
Hence set the completion callback only if spdk_nvme_ctrlr_disconnect()
succeeds.
Fixes issue #2632
