Tilman Schmidt 51370e5b21 gigaset: in file ops, check for device disconnect before anything else
When the device is disconnected, the dev structure goes away, so
trying to report another error via dev_printk is bound to oops.
To avoid that, first check whether the device is still connected
and return quietly if it isn't.

Impact: error handling
