net: s390: constify and use eth_hw_addr_set()
Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Make sure local references to netdev->dev_addr are constant.
