The test case assumed that the test target devices have 128 or more sequential write required zones and uses 128 as the minimum number of zones to write. This caused failure when the devices had a smaller number of sequential write required zones. To avoid the failure, count the actual number of sequential write required zones and use it if it is smaller than 128.
