From: Taehee Yoo <ap420073@xxxxxxxxx>
commit 4b793acdca0050739b99ace6a8b9e7f717f57c6b upstream.
When HSR interface is sending a frame, it finds a node with
the destination ethernet address from the list.
If there is no node, it calls WARN_ONCE().
But, using WARN_ONCE() for this situation is a little bit overdoing.
So, in this patch, the netdev_err() is used instead.
