destruct_poller had been used to destruct ctrlr after completing reset, but
we can remove destruct_poller and change reset processing to destruct ctrlr
after its completion by itself.
spdk_io_device_unregister() may fail spdk_for_each_channel(). Hence call
nvme_bdev_ctrlr_do_destruct() as the completion function of spdk_for_each_channel().
The first idea was to always run destruct_poller at nvme_bdev_ctrlr_destruct(),

Checking if destruct is false and setting destruct to true are
separated by mutex in remove_cb() and bdev_nvme_library_fini().
It was possible that multiple threads called nvme_bdev_ctrlr_destruct()
because the caller could call nvme_bdev_ctrlr_destruct() before
setting destruct to true after knowing it was false.
This patch ensures that nvme_bdev_ctrlr_destruct() is called only once.
Set ctrlr->destruct to true without releasing mutex after checking
if ctrlr->destruct is false.
If destruct is set to true before calling nvme_ctrlr_depopulate_namespaces(),
nvme_ctrlr_depopulate_namespace_done() may call nvme_bdev_ctrlr_destruct()
because it is likely that reference count is zero and destruct is true.
In this case, remove_cb() or bdev_nvme_library_fini() cannot call
nvme_bdev_destruct() after returning from nvme_ctrlr_depopulate_namespaces().
On the other hand, if a controller has no namespace,
nvme_ctrlr_depopulate_namespaces() does nothing and
nvme_ctrlr_depopulate_namespace_done() is not called. Hence
remove_cb() or bdev_nvme_library_fini() has to call nvme_bdev_destruct()
after returning nvme_ctrlr_depopulate_namespaces().
To unify both cases, initialize reference count to one as a sentinel value
and remove_cb() and bdev_nvme_library_fini() decrement reference count
and then calls nvme_bdev_ctrlr_destruct() if reference count is zero
after returning from nvme_ctrlr_depopulate_namespaces().
Additionally, add assert to check if reference count is not negative
to find bug in future.

The revert asynchronous API doesn't run as the *real* asynchronous
way, because the drive can only support synchronous module and only
1 session is supported. The reason why we added this API is that
RPC call has the default timeout value here, while the revert may
take over several minutes, the API itself doesn't short the revert
action, so just remove it and use the synchronous API instead.
The revert action will erase all the users data and bring the drive
back to the factory state, it should run in the synchronous mode,
so just remove the asynchronous API and we can increase the timeout
value when using RPC to call this API.

completes, we will try to call spdk_nvme_ctrlr_reset() on

While here, also add a check to skip the reset if the
