Subject: hsr: use netdev_err() instead of WARN_ONCE()
Patch-mainline: v5.7-rc1
Git-commit: 4b793acdca0050739b99ace6a8b9e7f717f57c6b
References: bsc#1176659

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.
