staging: comedi: das800: use cfc_handle_events() 



Use the comedi_fc helper function to automatically call the subdevice
(*cancel) function when needed and call comedi_event().

Also, remove the clearing of the event, comedi_event() does that.

In the Kconfig, COMEDI_DAS800 already selects COMEDI_FC.
