Separate bdev_nvme_reset() and _bdev_nvme_reset() by making
bdev_nvme_reset() call _bdev_nvme_reset_start(), and then
remove the ctx parameter from _bdev_nvme_reset().
This clarifies the next patch and reduces the size of the next patch.

The recent refactoring removed the destruct poller and change the
reset processing to destruct ctrlr after its completion by conditionally
sending message.
But differentiating callback function is difficult if we reset multiple
ctrlrs.
If nvme_bdev_ctrlr->destruct is set, any new reset cannot start. So we can
use an new variable and always execute the callback function.
Add an new variable pending_destruct to struct nvme_bdev_ctrlr, and set
pending_destruct if ctrlr->ref is zero and ctrlr->destruct is true, and
then start destruct ctrlr if ctrlr->destruct_after_reset is set after
clearing pending resets.

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.

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.
