block: Remove request_queue.nr_queues
Commit 897bb0c7f1ea ("blk-mq: Use proper cpumask iterator"; v4.6) removed the last use of request_queue.nr_queues from outside blk_mq_init_allocate_queue(). Remove this member variable to make struct request_queue smaller. This patch does not change any functionality.
