Subject: [PATCH 4/4] batman-adv: Disallow originator addressing within mesh layer

From: Linus Lüssing <linus.luessing@...om.ch>

For a host in the mesh network, the batman layer should be transparent.
However, we had one exception, data packets within the mesh network
which have the same destination as a originator are being routed to
that node, although there is no host that node's bat0 interface and
therefore gets dropped anyway. This commit removes this exception.
