ethernet: sky2/skge: 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.
Read the address into an array on the stack, then call
eth_hw_addr_set().
