If driver implements ndo_validate_addr,
core should check the mac address before ndo_set_mac_address.

ChangeLog:
v2 -> v3:
  - Use ndo_validate_addr() instead of is_valid_ether_addr()
    in dev_set_mac_address(), suggested by Jakub and Andrew.
  v2: https://lore.kernel.org/all/20240820140154.137876-1-shaojijie@huawei.com/
