staging: comedi: me4000: return void from ai_round_cmd_args()

Browse source

This function always succeeds. Change the return type to void and
remove the unnecessary error check in me4000_ai_do_cmd().

Move the function call in me4000_ai_do_cmd_test() from before Step 1
to Step 3 where the arguments are validated. There is no reason to
get the values if the previous steps fail.

Rename the function so it has namespace associated with the driver.
