When resuming an OSS device ask for the very same fragment settings as we did the first time
In OSS it is only possible to request fragment sizes that are powers of 2. However actually selected fragment sizes may be arbitrary values. This means that it is not always possible to request the same fragment size after a suspend that was used before the suspend because we simply cannot express it in the request. To work around that we should issue the same request as we did the first time.
