Pau Koning 816cd5b83e batman-adv: Fix NULL pointer dereference in DAT hash collision avoidance 
An entry in DAT with the hashed position of 0 can cause a NULL pointer
dereference when the first entry is checked by batadv_choose_next_candidate.
This first candidate automatically has the max value of 0 and the max_orig_node
of NULL. Not checking max_orig_node for NULL in batadv_is_orig_node_eligible
will lead to a NULL pointer dereference when checking for the lowest address.

This problem was added in 785ea1144182c341b8b85b0f8180291839d176a8
("batman-adv: Distributed ARP Table - create DHT helper functions").
