Set nvme bdev physical block size based value of NPWG and NAWUPF namespace
field.
The logic to set bdev phys_blocklen is based on how Linux nvme block driver
sets it. If the underlying nvme namespace supports NPWG/NAWUPF then bdev
phys_blocklen is set to min(npwg, nawupf)

By the next patch, nvme_io_channel will be used as an I/O channel
to a single nvme_bdev. This channel is created to a single
nvme_bdev_ctrlr and has a corresponding I/O qpair. nvme_io_path

Previously only a single thread could submit abort commands for admin
commands and it was the thread of the corresponding controller.
When we support multipath, we need to traverse the list of controllers
to which the target admin command is submitted. Threads of controllers
may be different.
On the other hand, the previous implementation made the I/O flow very
clean, but the I/O flow will not be clean if there are many controllers
and the subsystem does not have its thread.
This patch changes the policy so that any SPDK thread can submit abort
commands for admin commands.
Then when multipath is supported, we will be able to traverse the
list of controllers simply on the current thread to abort either I/O
command or admin command.
We already are able to submit any admin command on any thread anytime
including abort command. Hence this will not cause any issue.

We cannot rely on DSM/DEALLOCATE as a write zeroes
alternative, even if DLFEAT reports that deallocated
blocks will be read as all zeroes. DEALLOCATE is
advisory, meaning that blocks may not actually be
deallocated. In cases where they are not deallocated,
they will not be read back later as zeroes.
QEMU 6.0 started reporting DLFEAT as returning zeroes
for deallocated blocks but for some of our write
zeroes tests, blocks aren't actually deallocated.
We may be able to add quirks in the future if we know
that a controller reliably deallocates blocks, but
for now we need to revert this completely.
Note that since bdev/nvme module now does not support
write zeroes in any cases, we need to disable the
write zeroes call in the unit tests.

Clean up bdev_nvme_add_trid() by factoring out comparison of namespaces
and comparison of trids into helper functions, bdev_nvme_compare_namespaces()
and bdev_nvme_compare_trids(), respectively.
Then rename bdev_nvme_add_trid() by bdev_nvme_add_secondary_trid().
Rename is for clarification and clean-up is for the next patch.
The next patch will merge spdk_nvme_detach() and populate_namespaces_cb()
into the renamed bdev_nvme_secondary_trid(). Clean-up makes the
next patch simpler.
One note is that checking if the type of trid is not PCIe is done
by holding mutex now to prioritize clean up.

The API spdk_nvme_ctrlr_free_io_qpair() returns immediately if the
passed qpair is NULL, but calling spdk_nvme_ctrlr_free_io_qpair()
with NULL should be avoided.
This patch cleans up the code to ensure that nvme_ch->qpair is NULL if
disconnected and spdk_nvme_ctrlr_free_io_qpair() is called only if
nvme_ch->qpair is not NULL.
Then add a test scenario that two reset requests were submitted
simultaneously and the first reset request failed and then the second
reset request also failed. This verifies the refactoring done in the
next patch.

Add support for zoned namespaces in the bdev/nvme module.
Query the namespace type, and if a zoned namespace is found, set the
bdev struct members needed by the bdev_zone.h APIs.
Note that while vbdev_zone_block and bdev_ocssd have zone locks,
bdev/nvme does not need any kind of zone lock, because NVMe ZNS
supports append natively.
The whole point of the zone append command is that you don't need any
locks, even when having multiple writers, since the drive will return
back the Assigned LBA where the blocks were actually written.
If a SPDK application will utilize writes instead of zone appends,
the SPDK application itself will need a per zone lock in order to
make sure that there is only one outstanding write.
Adding zone locks in bdev/nvme would reduce the performance of zone
appends, for no reason at all.

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.

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
attached as quickly as possible. Controller initialization
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.
