btrfs: zoned: use sector_t for zone sectors

[ Upstream commit d734492a14a2da6e7bcce8cf66436a9cf4e51ddf ]

We need to use sector_t for zone_sectors, or it would set the zone size
to zero when the size >= 4GB (= 2^24 sectors) by shifting the
zone_sectors value by SECTOR_SHIFT. We're assuming zones sizes up to
8GiB.
