net: constify netdev->dev_addr
Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. We converted all users to make modifications via appropriate
helpers, make netdev->dev_addr const.
The update helpers need to upcast from the buffer to
struct netdev_hw_addr.
