This will make us easier to maintain the operation to delete
nvme_bdev_ctrlr and its trids. The added unit test cases guard us
from degradation.

On some platforms, GCC identifies that opts.io_queue_requests is used
uninitialised in bdev_nvme_create_qpair due to the stub function
spdk_nvme_ctrlr_get_default_io_qpair_opts which would normally zero the
qpair opts. Whether the warning appears is likely to be determined by
how effectively the platform garbage collects unused code.
Replace the stub with a minimal implementation that zeros the qpair
opts to avoid the warning.

When multipath is supported, nvme_bdev will be got via bdev_subsystem.
To make such change transparent, add a helper function
nvme_bdev_ns_to_bdev() and use it for some cases.

By the recent changes, the linked list nvme_ns->bdevs has only a
single bdev at the maximum. Hence replace it by the pointer
nvme_ns->bdev, and remove the linked list pointer nvme_bdev->tailq.

By the last changes, not only standard namespace but also ocssd
namespace has only one nvme_bdev, and standard namespace processes
only the head of nvme_ns->bdevs.
This patch changes the common and standard namespace specific
part to process only the head of nvme_ns->bdevs.
The following patch will replace the linked list nvme_ns->bdevs
by the pointer nvme_ns->bdev.
Add a particular error case that nvme_bdev is failed to create even
if ctrlr has one namespace. If ctrlr has one namespace but the
corresponding bdev is failed to create, nvme_ns->populated should
be false and hence nvme_ns->bdevs should not be accessed. However
the code had not assumed such case.
