net: create netdev->dev_addr assignment helpers
Recent work on converting address list to a tree made it obvious we need an abstraction around writing netdev->dev_addr. Without such abstraction updating the main device address is invisible to the core. Introduce a number of helpers which for now just wrap memcpy() but in the future can make necessary changes to the address tree.
