net: dev: Fix non-RCU based lower dev walker
netdev_walk_all_lower_dev is not properly walking the lower device
list. Commit 1a3f060c1a47 made netdev_walk_all_lower_dev similar
to netdev_walk_all_upper_dev_rcu and netdev_walk_all_lower_dev_rcu
but failed to update its netdev_next_lower_dev iterator. This patch
fixes that.
Fixes: 1a3f060c1a47 ("net: Introduce new api for walking upper and
lower devices")
