staging: comedi: cb_das16_cs: fix analog output subdevice init
The analog output subdevice is only available on the -AO version of the DAS16/16 device and the number of channels is provided in the boardinfo. Make sure the subdevice is marked as unused for devices that do not support the analog out.
