staging: comedi: hwdrv_apci3200: properly validata the ai cmd->start_arg
The async command 'arguments' should be trivially validated in Step 3 of
the (*do_cmdtest) not Step 2b. Move the validataion in this driver to the
proper place.
This driver supports two cmd->start_src values, TRIG_NOW and TRIG_EXT.
TRIG_NOW sources should always have an arg of 0. The arg for TRIG_EXT
sources is driver specific.
Properly validate the cmd->start_arg based on the cmd->start_src. Remove
the noise when the arg is invalid and modify the cmd->start_arg so that
a valid value is returned to the user.
