batman-adv: fix counter for multicast supporting nodes
commit e8829f007e982a9a8fb4023109233d5f344d4657 upstream.
A miscounting of nodes having multicast optimizations enabled can lead
to multicast packet loss in the following scenario:
If the first OGM a node receives from another one has no multicast
optimizations support (no multicast tvlv) then we are missing to
increase the counter. This potentially leads to the wrong assumption
that we could safely use multicast optimizations.
Fixings this by increasing the counter if the initial OGM has the
multicast TVLV unset, too.
