staging: comedi: amplc_dio200_common: fix the cmd->start_arg use
This driver supports two cmd->start_src values, TRIG_NOW and TRIG_INT. TRIG_NOW
sources should always have an arg of 0. For TRIG_INT sources, the cmd->start_arg
is actually the valid trig_num that is passed to the async (*inttrig) callback.
This driver trivially validates the arg for both sources to be 0.
Refactor the (*inttrig) so that the cmd->start_arg is used to check the trig_num
instead of the open coded value.
For aesthetics, refactor the (*do_cmd) to use if/else instead of the switch when
handling the cmd->start_src.
