staging: comedi: ssv_dnp: use comedi_dio_update_state()
commit f6b316bcd8c421acd6fa5a6e18b4c846ecb9d965 upstream.
Use comedi_dio_update_state() to handle the boilerplate code to update
the subdevice s->state.
Also, fix a bug where the state of the channels is returned in data[0].
The comedi core expects it to be returned in data[1].
