block: Reduce the amount of memory required per request queue
Instead of always allocating at least nr_cpu_ids hardware queues per request
queue, reallocate q->queue_hw_ctx if it has to grow. This patch improves
behavior that was introduced by commit 868f2f0b7206 ("blk-mq: dynamic h/w
context count").
