From: Ido Schimmel <ido...@mellanox.com>
netdev_next_lower_dev() returns NULL when we finished traversing the
adjacency list ('iter' points to the list's head). Therefore, we must
start traversing the list from the first entry and not its head.
Fixes: 1a3f060c1a47 ("net: Introduce new api for walking upper and lower
devices")
