[PATCH rdma-next 2/3] mlx5: use dev_addr_mod()

[Jakub Kicinski <kuba@kernel.org>]

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.
