bdev/nvme: Consolidate populate_namespace_cb() calls for error cases into connect_attach_cb()

Browse Source 
Consolidate populate_namespaces_cb() calls for error cases into
connect_attach_cb().  Then remove ctx parameter from
bdev_nvme_add_secondary_trid() because it is not necessary now.

The next patch will inline _nvme_bdev_ctrlr_create() into
nvme_bdev_ctrlr_create().
