There are two changes. First, if md module is not loaded, it gives error when reading speed_limit_max. So read the value after loading md module which is done in do_setup Second, sometimes the test reports error sync action doesn't happen. But dmesg shows sync action is done. So limit the sync speed before test. It doesn't affect the test run time. Because check wait sets the max speed before waiting sync action. And recording speed_limit_max/min in do_setup.
