If omp::directive attribute argument starting with the opening ( is not a balanced
token sequence, then cp_parser_skip_balanced_tokens (parser, 1) returns 1,
but the code was subtracting 2 from it and iterating until it was 0, so for the
non-balanced case it iterated from (size_t) -1 down to 0.
The following patch just diagnoses that as an error.
