staging: comedi: usbduxfast: remove #include "comedi_fc.h"

As preparation for removal of "comedi_fc.h", replace calls to the
`cfc_check_trigger_...` functions from "comedi_fc.h" with the
replacement `comedi_check_trigger_...` functions from "../comedidev.h"
and remove the inclusion of "comedi_fc.h".
