Introduce the blkdev_nr_zones() helper function to get the total
number of zones of a zoned block device. This number is always 0 for a
regular block device (q->limits.zoned == BLK_ZONED_NONE case).
Replace hard-coded number of zones calculation in dmz_get_zoned_device()
with a call to this helper.
