mac80211: Learn about mesh portals from multicast traffic
Mesh portals proxy traffic for nodes external to the mesh. When a
proxied frame is received by a mesh interface, it should update its mesh
portal table. This was only happening for unicast frames. With this
change we also learn about mesh portals from proxied multicast frames.
