ipv6: fix handling of throw routes
It's the same problem that previous fix about blackhole and prohibit routes.
When adding a throw route, it was handled like a classic route.
Moreover, it was only possible to add this kind of routes by specifying
an interface.
Before the patch:
$ ip route add throw 2001::2/128
RTNETLINK answers: No such device
$ ip route add throw 2001::2/128 dev eth0
$ ip -6 route | grep 2001::2
2001::2 dev eth0 metric 1024
After:
$ ip route add throw 2001::2/128
$ ip -6 route | grep 2001::2
throw 2001::2 dev lo metric 1024 error -11
