[DECNET] address: Convert to new netlink interface
Extends the netlink interface to support the __le16 type and converts address addition, deletion and, dumping to use the new netlink interface. Fixes multiple occasions of possible illegal memory references due to not validated netlink attributes. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
