net: ipv6: Do not add multicast route for l3 master devices
L3 master devices are virtual devices similar to the loopback device. Link local and multicast routes for these devices do not make sense. The ipv6 addrconf code already skips adding a linklocal address; do the same for the mcast route. Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
