A few patches including this patch will remove nvme_ns->ref by
nvme_ns->populated and nvme_ns->bdev and remove nvme_ns->ref.
In this patch, set nvme_ns->populated to true when nvme_ns->ref is
incremented, i.e., nvme_ns is available. nvme_ctrlr_populate_namespace_done()
clears nvme_ns->populated if creating bdev failed by memset().
And add assert to nvme_ctrlr_depopulate_namespace_done() to ensure
nvme_ns->populated is false when nvme_ctrlr_depopulated_namespace_done()
is called.
