The queue size calculation is currently based on "max_tokens" rather than
"max_work_queues_size". This is resulting in the queue size being
incorrectly configured when using the script to configure devices bound to
the IDXD kernel driver.
This patch fixes this miscalculation so devices are configured with
appropriate queue size.
