scsi: ufs: core: Fix divide by zero in ufshcd_map_queues()

Before calling blk_mq_map_queues(), the mq_map and nr_queues belonging to
struct blk_mq_queue_map must have a valid value.

If nr_queues is set to 0, the system may encounter a divide by zero
depending on the type of architecture.

    blk_mq_map_queues() -> queue_index()
