Seems fine. Actually, since the message is freed anyhow, the call to
genlmsg_cancel is *completely* unnecessary, I just put it in to make it
nest better and not rely on it not having side effects.

But why did you call the label differently? :)

Because out is already used in this case, and I didn't want to change all 
of the other occurrences of nla_put_failure.  It's a bit sloppy though, 
because this code is the actual nla_put_failure.  I can change it if you 
prefer.
