From: Naohiro Aota <naohiro.aota@xxxxxxx>
Introduce some zone related helper functions: _zone_type(),
_require_zoned_device(), and _require_non_zoned_device(). They all take a
device path as an argument.
_zone_type() return the zone type of the device according to the value
returned from "/sys/block/<disk>/queue/zoned". See
Documentation/ABI/testing/sysfs-block for a detail.
_require_zoned_device() checks if the device is zoned. If not, it skips the
current test. _require_non_zoned_device() does the opposite.
