The following patches will remove nvme_ns->ref and use nvme_ns->populated
and nvme_ns->bdev instead because nvms_ns->ref is two at most and
each count of nvme_ns->ref corresponds to nvme_ns->populated or
nvme_ns->bdev.
To do that, we need to ensure nvme_ns->populated is cleared after
spdk_bdev_unregister() is called, otherwise nvme_bdev_ctrlr_destruct()
is called twice.
However OCSSD namespace had used nvme_ns->populated to free resource
after getting log page completes.
To keep such deferral, add the depopulate_pending flag to struct bdev_ocssd_ns
and use it. Then clear nvme_ns->populated in bdev_ocssd_free_namespace()
after spdk_bdev_unregister().
