Subject: net: usb: use eth_hw_addr_set() instead of ether_addr_copy()
Patch-mainline: v5.16-rc1
Git-commit: af804e6db9f60b923ff5149d9bf782e0baa82a2b
References: jsc#PED-1565

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.

Convert net/usb from ether_addr_copy() to eth_hw_addr_set():

  - ether_addr_copy(dev->dev_addr, np)
  + eth_hw_addr_set(dev, np)
