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.
