    Fix warning in posix/bug-regex31.c.

    This patch fixes a "set but not used" warning in posix/bug-regex31.c.

    A variable res stored an indication of whether the test behaved as

    expected, but was then ignored and the test returned 0 unconditionally

    (as an mtrace test, the auxiliary test for leaks could still have

    failed if that bug was present).  This patch makes the test return

    res.

    Tested for x86_64.

            * posix/bug-regex31.c (main): Return RES not 0.
