staging: comedi: usbdux: fix the cmd->start_arg use
For all cmd->start_src values this driver trivially validates that the cmd->start_arg is 0. For a TRIG_INT source, the cmd->start_arg is actually the valid trig_num that is used by the async (*inttrig) callback. Refactor the (*inttrig) functions so that the cmd->start_arg is used to check the trig_num instead of the open coded values.
