68a8502f1c bdev/nvme: Remove nvme_ns->ref and use nvme_ns->populated and nvme_ns->bdev instead
As said in the previous patches, nvme_ns->ref is 2 at most, and
first is for populating namespace and second is for nvme_bdev.
On the other hand, nvme_ns->populated is for populating namespace
and nvme_ns->bdev is for nvme_bdev.

Preparation was done by the preceding patches. Let's remove nvme_ns->ref
and use nvme_ns->populated and nvme_ns->bdev instead.

We have unit tests for both normal case and shutdown case now.
So regression will be avoided.

These changes will be helpful for the following patches to support
multipath.

b1d6c2f3cb bdev/ocssd: Add ocssd_ns->depopulate_pending to complete pending depopulation
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().

f26d6c73e1 bdev/nvme: Set nvme_ns->populated to true just after nvme_ns is available
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.

8cc81fa07a bdev/nvme: Inline nvme_bdev_ns_detach()
The nvme_ns->ref was added to nvme_bdev_ns to support both multipath
and OCSSD range. OCSSD range was to split a namespace into multiple
partitions.

However, OCSSD range was not used and removed to simplify multipath.

When namespace is not split, nvme_ns->ref is 2 at the maximum. First is
for populating namespace and second is for nvme_bdev. nvme_ns->populated
is for populating namespace and nvme_ns->bdev is for nvme_bdev.
Hence we can use nvme_ns->populated and nvme_ns->bdev directly instead of
nvme_ns->ref.

A few patches from this remove nvme_ns->ref and use nvme_ns->populated
and nvme_ns->bdev instead.

dThis patch inlines nvme_bdev_ns_detach() into the callers and remove it.

The following patches will adjust the locations to update nvme_ns->populated
and nvme_ns->bdev and then remove nvme_ns->ref.

Removing nvme_ns->ref will be helpful to associate multiple namespaces
into a single nvme_bdev for multipath.

nvme_bdev_ns_to_bdev() was introduced because nvme_ns->bdev may be
removed to support multipath. However, it is unlikely now.

Hence it is easier to read to stop using nvme_bdev_ns_to_bdev() and

bd65fef240 bdev/ocssd: Add ocssd_bdev parameter to I/O submit functions
nvme_bdev passes not spdk_bdev_io but nvme_bdev_io pointer to I/O
submit functions, and gets spdk_bdev_io pointer from nvme_bdev_io
pointer in its completion callback functions.

This is very clean because spdk_bdev_io is processed by the generic bdev
layer and nvme_bdev_io is processed by the NVMe bdev module.

The patch series changes ocssd_bdev to pass not spdk_bdev_io but
bdev_ocssd_io pointer to its I/O submit functions.

This patch is the first of the series and add ocssd_bdev parameter
to I/O submit functions. ocssd_bdev pointer is got from
bdev_io->bdev->ctxt. Hence this patch removes one dependency on
spdk_bdev_io.

One noticeable small change is that get_zone_info() gets zone_info
from not bdev_io->bdev but nvme_bdev->disk to advance removing
the dependency on spdk_bdev_io.
