SCLang: tidy duplicated error message

[JordanHendersonMusic]

Purpose and Motivation

This is uncontroversial and can be quickly reviewed.

Cannot have more than 255 arguments to a function, but the message was printed twice. This removes that duplication.
Some code to test, it should only show one error message after this PR.

That looks uncontroversial. Good eye.

[telephon]

even if it is uncontroversial, someone needs to run one compile and check if it breaks nothing. (I can't, because for me the build is stil broken)

Unless it's a typo for something else, like checking mVarlist?

I think it was your contribution, Julian @telephon . Maybe you remember if was just repetition, or was checking another aspect?

(I can build and run on linux if needed)

[telephon]

Ah, I don't remember why it seemed necessary at that time. Yes, if you test compile it on linux and see if it works as intenden, it should be fine.

Looks like there may have just been some mixup in commit revisions and the change ended up in two commits.
