staging: comedi: adl_pci9118: tidy up digital output subdevice init

For aesthetics, add some whitespace to the digital output subdevice init.

Remove the SDF_GROUND and SDF_COMMON subdev_flags. These flags only apply
to analog subdevices.

Remove the 'len_chanlist' init, this subdevice member is only used with
subdevices that support async commands.
