ipv4: validate IPV4_DEVCONF attributes properly
As the IPV4_DEVCONF netlink attributes are not being validated, it is
possible to use netlink to set read-only values like mc_forwarding. In
addition, valid ranges are not being validated neither but that is less
relevant as they aren't in sysctl.
To avoid similar situations in the future, define a NLA policy for
IPV4_DEVCONF attributes which are nested in IFLA_INET_CONF.
