netlink: specs: rt-link: remove implicit structs from devconf

devconf is even odder than SNMP. On input it reports an array of u32s
which seem to be indexed by the enum values - 1. On output kernel
expects a nest where each attr has the enum type as the nla type.

sub-type: u32 is probably best we can do right now.
