This commit always delivers multicast traffic to host. Without this change, host will not be able to receive link-local and mesh-local multicast traffic, even the host subscribes to some multicast addresses in these scopes. Note that this does not change the host forwarding rules, as link-local and mesh-local traffic are not supposed to be forwarded to adjacent links.
