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(),
but this patch will be simpler and more intuitive.

Cache size of mempool is not based on SPDK thread but DPDK thread,
i.e. CPU core. So replace spdk_thread_get_count() by
spdk_env_get_core_count() to determine cache size of mempool in
spdk_bdev_initialize().
Besides, allocate and free stub cores at the corresponding unit tests.

Using not FAILED but ABORTED for the completion status of the I/Os
aborted by reset will be reasonable and is done in this patch.

The last patch ensures that the parent I/O terminate with failure
before continuing splitting process if one of child I/O failed.
This simplifies abort operation for I/O splitting.
Then we can use bdev_abort() and bdev_abort_io() nestedly.
Add necessary unit test together.

Previously, bdev_io_split_done() had continued splitting process
even if the status became failed. To abort split I/O, this patch
changes bdev_io_split_done() to terminate with failure before
continuing splitting process if the status became failed. Add
necessary unit test together.

This is a preparation to abort split I/Os. To abort any I/O by

When the target I/O is controlled by QoS, the abort request is
submitted on the same channel that the target I/O is submitted.
By using this, add a helper function bdev_abort_queued_io(), and
change _bdev_io_submit() to call bdev_abort_queued_io(), and
call _bdev_io_complete_in_submit() with success if bdev_abort_queued_io()
returned true when QoS is enabled on the corresponding channel.
Add necessary unit test together.
Update unit test accordingly, especially, update stub_submit_request()
to abort the matched I/O, update io_during_io_done() because we need to
know not boolean but the exact completion status now, and update
basic_qos() to reset the rate limit to test the abort I/O feature.
