batman-adv: don't add TEMP clients belonging to other backbone nodes

Browse source 
The "early client detection" mechanism must not add clients belonging
to other backbone nodes. Such clients must be reached by directly
using the LAN instead of the mesh.

This was introduced by 30cfd02b60
("batman-adv: detect not yet announced clients")
