Don't suggest a semicolon when the type is not unit (#12116)

Don't suggest a semicolon when the type is not unit

This hint message is printed when a function receives too many
arguments. It doesn't make sense when the return type of the function is
not unit:

    Line 2, characters 2-11:
    2 |   (+) 1 2 3
          ^^^^^^^^^
    Error: The function '(+)' has type int -> int -> int
           It is applied to too many arguments
    Line 2, characters 8-10:
    2 |   (+) 1 2 3
                ^^
      Hint: Did you forget a ';'?

This removes the message when it is not applicable.
