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()
