s390/3215: fix hanging console issue
The ccw_device_start in raw3215_start_io can fail. raw3215_try_io does not check if the request could be started and removes any pending timer. This can leave the system in a hanging state. Check for pending request after raw3215_start_io and start a timer if necessary. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
