[v14,6/8] qemu-iotests: test new zone operations

Commit Message

Sam Li Dec. 19, 2022, 8:05 a.m. UTC

We have added new block layer APIs of zoned block devices. Test it as
follows: Run each zone operation on a newly created null_blk device
and see whether the logs show the correct zone information. By:
$ ./tests/qemu-iotests/tests/zoned.sh
