[PATCH net-next 05/12] ethernet: aquantia: 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.
Use an array on the stack, then call eth_hw_addr_set().
eth_hw_addr_set() is after error checking, this should
be fine, error propagates all the way to failing probe.
