ser_gigaset: convert mutex to completion
The ser_gigaset ISDN driver was using a mutex in its close() method for waiting for other running ldisc methods to finish. That's what completions are for. Incidentally, this also avoids a spurious "BUG: lock held at task exit time" message when the driver's userspace daemon daemonizes itself.
