net: ethernet: support of_get_mac_address new ERR_PTR error
There was NVMEM support added to of_get_mac_address, so it could now
return ERR_PTR encoded error values, so we need to adjust all current
users of of_get_mac_address to this new fact.
While at it, remove superfluous is_valid_ether_addr as the MAC address
returned from of_get_mac_address is always valid and checked by
is_valid_ether_addr anyway.
Fixes: d01f449c008a ("of_net: add NVMEM support to of_get_mac_address")
