[Olsr-dev] Smartgateway

[Teco Boot]

Another problem. 

I have a 3 node network:
 173  (is gw)
 179
 166

179 was GW before (days ago).

179 and 166 have a tunnel to 173 (OK).

173 has still selected 179 as GW. It should deselect and 
delete the tunnel, because 179 withdrawn the HNA. 

Cleanup should be performed in olsr_delete_gateway_entry in hna_set.c
No idea why is is still there.
Maybe move the cleanup in the regular GW selection routine?
Condition: current GW must have valid path and must have the SGW HNA entry.
