netlink: Remove compat API for nested attributes
Removes all _nested_compat() functions from the API. The prio qdisc no longer requires them and netem has its own format anyway. Their existance is only confusing. Resend: Also remove the wrapper macro. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
