3.5.7.10 -stable review patch.  If anyone has any objections, please let me 
know.

------------------

From: Andrey Vagin <ava...@openvz.org>

commit ae5fc98728c8bbbd6d7cab0b9781671fc4419c1b upstream.

Follow the common pattern and define *_DIAG_MAX like:

        [...]
        __XXX_DIAG_MAX,
};

Because everyone is used to do:

        struct nlattr *attrs[XXX_DIAG_MAX+1];

        nla_parse([...], XXX_DIAG_MAX, [...]
