The test script erroneously falls back to using libzbc for finding out
the max_open_zones setting if the device being tested is not a SCSI
device. This causes false positives if libzbc is not installed in the
test system. To fix, unless the option to use libzbc is explicitly set,
set this value to 0 for non-SCSI devices to let fio find the actual
max_open_zones value using the system block interface.
