Undo misguided distinction WRT deciding if a warning is an error or a warning.

A Warning is a warning, diagnostics DTRT. Cosmetic correction from fallout for

        * errors.c (gfc_notify_std): As originally stated but improperly
        changed, disregard warnings_are_errors for deciding which buffer
        to use for warnings.
