[PATCH blktests v3 03/13] block/004: Adjust fio conditions for zoned block devices

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.
Set CAN_BE_ZONED flag to run this test case for zoned block devices.
