diag: warn about missing first netlink attribute
The first netlink attribute (value 0) must always be defined as none/unspec. This is correctly done in inet_diag.h, but other diag interfaces are wrong. Because we cannot change an existing API, I add a comment to point the mistake and avoid to propagate it in a new diag API in the future.
