    fcmatch: Set FcResultMatch at the end if the return value is valid.
    
    In the previous code, the result of 'result' in the argument for
    FcFontSetSort() and FcFontSetMatch() wasn't predictable and not reliable to
    check if the return value is valid or not. this change is to ensure if it's
    performed successfully.
