Current fio implementation does not handle zones in closed condition as
write target zones. When the device has max_active_zones limit, the
write to other zones may cause errors by exceeding the limit, since the
zones in closed condition consume the device resource for the
max_active_zones limit.
To avoid the error, handle the zones in closed condition as write target
in same manner as the zones in open condition when the device has the
max_active_zones limit. At the job start, check each condition of the
zones in the IO ranges and if it has closed condition, pass the zone
to zbd_write_zones_get() in same manner as the zones in open condition.
