Lorenzo Colitti 6202fe4eec net: ipv6: Don't purge default router if accept_ra=2 
[ Upstream commit 3e8b0ac3e4 ]

Setting net.ipv6.conf.<interface>.accept_ra=2 causes the kernel
to accept RAs even when forwarding is enabled. However, enabling
forwarding purges all default routes on the system, breaking
connectivity until the next RA is received. Fix this by not
purging default routes on interfaces that have accept_ra=2.
