For a random write pattern to a zoned block device, fio requires --direct=1
and --zonemode=zbd options as well as deadline I/O scheduler to be
specified. Specify these options and set the I/O scheduler if the target
device is a zoned block device. Before doing that, also make sure that the
deadline scheduler is available and that fio supports the zbd zone mode.
