3.5.7.6 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Romain Kuntz <r.kuntz@ipflavors.com>

commit 85da53bf1c336bb07ac038fb951403ab0478d2c5 upstream.

The tests on the flags in addrconf_get_prefix_route() does no make
much sense: the 'noflags' parameter contains the set of flags that
must not match with the route flags, so the test must be done
against 'noflags', and not against 'flags'.
