====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Use DEBUG_NET_WARN_ON_ONCE() instead of WARN_ON() from the tproxy
   datapath, a recent bug found a way to reach WARN_ON from datapath
   due to insufficient validation of xt_TPROTO checkentry.
   From Fernando F. Mancera.

2) Similar to previous patch to replace WARN_ON_ONCE by
   DEBUG_NET_WARN_ON_ONCE() for connlimit. Not known issue, but
   since this patch has been around for a while, let's merge it.
   Also from Fernando.

3) Move nf_tables harware offload commit path after chain blob
   and audit to reduce chances of leaving the hardware in
   inconsistent state.

4) Add missing vzeroupper to nf_tables pipapo AVX2 to address
   performace degradation to later user of SSE code,
   from Eric Biggers.

5) Remove pr_debug() in x_tables extensions, a recent bogus found a
   way to print a unsanitized string in xt_IDLETIMER, many of these
   pr_debug() calls are there for historical reasons.

6) Use pr_info_ratelimited() in x_tables .checkentry.

7) Fix an imbalance in module refcount due to incorrect override
   expression logic with sets. Remove unnecessary clone in control
   plane, use the existing expressions provided by set or dynset
   expression. Release override expressions only.

8) Tigthen nf_tables device name removal, it is possible to remove
   prefix strings with exact device name. From Fernando F. Mancera.

9) Set on the set dead bit earlier, otherwise it is possible to
   call .commit on deleted sets. This also addresses the
   re-introduction of a bug.
