We need to pass bio only when the reset request came from the upper
layer. Previously, bdev_nvme_reset() called _bdev_nvme_reset() and
_bdev_nvme_reset() had the second parameter, ctx, to pass bio to
for_each_channel(). However, it was not clean.
Let's separate bdev_nvme_reset() which processes a reset request
came from the upper layer and _bdev_nvme_reset() which proesses
an internal reset request by adding a helper function
_bdev_nvme_reset_start().
The next patch will remove the second parameter, ctx, from
_bdev_nvme_reset() for clarification and further refactorings.

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.

nvme_bdev_ctrlr is valid while populating namespaces of the
nvme_bdev_ctrlr regardless of the result. nvme_bdev_ns holds
nvme_bdev_ctrlr by its pointer, ctrlr. Hence it is not necessary for
nvme_ctrlr_populate_namespaces_done() to use nvme_bdev_ctrlr_get_by_name()
to get nvme_bdev_ctrlr.
To simplify the code, add nvme_bdev_ctrlr parameter to
nvme_ctrlr_populate_namespaces_done() and remove the
nvme_bdev_ctrlr_get_by_name() call from nvme_ctrlr_populate_namespaces_done().

In nvme_bdev_ctrlr_create, calloc will be called with a zero size
allocation request if the number of namespaces is zero. The behaviour
is implementation defined if the size of the space requested is zero -
calloc will either return a pointer that mustn't be dereferenced, or
NULL. If NULL is returned, the nvme_bdev_ctrlr_create will fail.
Only call calloc if there are a non-zero number of namespaces.
Otherwise, leave the namespaces pointer with a NULL value. All
references to namespaces[] are either known to be safe, or occur
in the context of looping through the namespaces which will be
skipped if the count is zero. The exception to this is in
vbdev_opal_create, where an assert has been added to match
equivalent code in bdev_ocssd_create_bdev.
Tested by running unit tests on a system that returns a null pointer
for a zero size allocation.

When we do detect new devices, we would like to get them

requires a non-trivial number of admin commands, and when
using async probe, it means that after we have detected
a new device, it will take many iterations of calling
spdk_nvme_probe_poll_async() before the controller is
fully attached.
So when we are actively probing a probe_ctx, create
a new poller that is solely responsible for probing
that context at a much higher frequency.

Add an new variable is_failed to struct nvme_bdev_ctrlr_trid, and
set it to true when starting failover or when failover failed, or
set it to false when initializing or failover succeeded.
Then add an new failover trid before all failed trids.
The test log showed that many failover failed because new trid was
added after failed trids.

We do not know failover is attempted from which path to which path.
Get these information by NOTICELOG.
Failover or reset is serialized by the flag ctrlr->resetting and
ctrlr->failover_in_progress.
Hence it is enough to add such information only to start.

bdev_nvme_submit_request() calls bdev_nvme_get_buf_cb() directly
when the buffer is already allocated. This is for performance improvement
but will be helpful for the upcoming multipath feature to retry
read I/O submission because buffer should be allocated only once.
By reading the code a little more critically, bdev_nvme_submit_request()
can call bdev_nvme_readv() directly in this case, and do in this patch.

nvme_bdev_ctrlr pointer is already cached to nvme_io_channel.
Hence let's remove it from the helper functions, bdev_nvme_create_qpair()
and bdev_nvme_destroy_qpair().
The following minor fixes are done together in this patch.
Fix the error paths of bdev_nvme_create_qpair() because
bdev_nvme_destroy_qpair() cannot be used as is in this case.
When calling bdev_ocssd_destroy_io_channel(), check if nvme_ch->ocssd_ch
is not NULL instead of spdk_nvme_ctrlr_is_ocssd_supported().
Cache nvme_bdev_ctrlr to nvme_io_channel just before calling
bdev_nvme_create_qpair() because the pointer is more associated
with qpair.

When a device is removed, we should use the remove_cb
that was specified when the device was originally probed
and attached, if one was set.
Also add a new spdk_nvme_ctrlr_set_remove_cb API. This
can be used for cases where a different remove_ctx is
desired than was specified for the probe call. This
also enables setting a remove_cb when using connect APIs
which do not have a way currently to provide a remove_cb.
This also requires fixing the bdev nvme module, which
was depending on the previously errant behavior.
Fixes issue #1715.

It is recommended to read CSTS when there is a timeout.
If CSTS.CFS (Controller Fatal Status) is set, we should
reset the controller.
But if an admin command on a fabrics controller times
out, reading CSTS submits another fabrics command that
could also timeout. Even worse, we are recursively
polling the admin queue for completions in this case.
Fixes issue #1716.

In other places, nvme_ns->populated has been used to check an namespace
is active for an existing nvme_bdev_ctrlr. We do not need to call
spdk_nvme_ctrlr_is_active_ns() again. Follow it in this patch.
Besides, factor out the namespace comparison into a small helper
function bdev_nvme_compare_ns(). It will be used to check if two
controllers have the common namespace for ANA multipath.

Previously, we separated two cases, creating an new nvme_bdev_ctrlr
and adding an new path to an existing nvme_bdev_ctrlr as early as
possible.
However, we can merge creating an new connection between these two
cases. In this patch, connect_attach_cb() calls bdev_nvme_add_trid()
and then calls spdk_nvme_detach() if the nvme_bdev_ctrlr whose name is
ctx->base_name already exists.
This will simplify ANA multipath feature.
