blk-mq: Keep set->nr_hw_queues and set->map[].nr_queues in sync
blk_mq_map_queues() and multiple .map_queues() implementations expect that
set->map[HCTX_TYPE_DEFAULT].nr_queues is set to the number of hardware
queues. Hence set .nr_queues before calling these functions. This patch
fixes the following kernel warning:
WARNING: CPU: 0 PID: 2501 at include/linux/cpumask.h:137
