In preparation for adding zone write plugging, modify blk_revalidate_disk_zones() to get the capacity of zones of a zoned block device. This capacity value as a number of 512B sectors is stored in the gendisk zone_capacity field. Given that host-managed SMR disks (including zoned UFS drives) and all known NVMe ZNS devices have the same zone capacity for all zones blk_revalidate_disk_zones() returns an error if different capacities are detected for different zones.

That again. We should never have allowed zones with different sizes. Anyway.
