staging: comedi: comedi_test: ao subdevice does not support async commands
The comedi_subdevices array is kzalloc()'d so the async command callbacks do
not need to be set to NULL when the analog output subdevice is initialized.
Also, remove the initialzation of the subdevice 'len_chanlist' since this
value is only used by the async commands. The core will default it to 1.
