block: introduce bdev_zone_no helper
Add a generic bdev_zone_no() helper to calculate zone number for a
given sector in a block device. This helper internally uses disk_zone_no()
to find the zone number.
Use the helper bdev_zone_no() to calculate nr of zones. This lets us
make modifications to the math if needed in one place.
