Yeah, I guess we can't show a missing attribute of 0 now - bad_attr is
a pointer so no problem there.

I think I'll leave it like this - if anyone really wants to say
"attribute 0 is missing" then we can add a flag later... The UAPI does
take this into account by not including the attribute at all if the
data is invalid, so 0 in the userspace API can be done
