V4L/DVB (9114): dib0700: fix bad assignment of dib0700_xc5000_tuner_callback after return call
Put callback definition before function return and cleanup callback: Fix a bug where the xc5000 callback was being set *after* the return call (essentially resulting in dead code). Also cleanup the callback function to detect unknown commands.
