batman-adv: Avoid nullptr dereference in bla after vlan_insert_tag
commit 10c78f5854d361ded4736c1831948e0a5f67b932 upstream.
vlan_insert_tag can return NULL on errors. The bridge loop avoidance code
therefore has to check the return value of vlan_insert_tag for NULL before
it can safely operate on this pointer.
