batman-adv: Avoid nullptr dereference in dat after vlan_insert_tag
commit 60154a1e0495ffb8343a95cefe1e874634572fa8 upstream.
vlan_insert_tag can return NULL on errors. The distributed arp table code
therefore has to check the return value of vlan_insert_tag for NULL before
it can safely operate on this pointer.
