staging: comedi: usbduxfast: use cfc_check_trigger_arg_*() helpers
Use the new helpers in the step 3 tests of usbduxfast_ai_cmdtest(). Also, remove some debug noise. Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Cc: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
