[S390] qdio: Repair timeout handling for qdio_shutdown
If qdio shutdown runs in parallel with a channel error, the qdio_timeout_handler might not be triggered. In this case neither state INACTIVE nor state ERR is reached and the following wait_event hangs forever. Solution: do not make use of ccw_device_set_timeout(), but add a timeout to the following wait_event. And make sure, wake_up is called in case of an i/o error on the qdio-device.
