Netfilter fixes for net

The following patchset contains the first batch of Netfilter fixes for
your net tree:

1) Fix splat with IPv6 defragmenting locally generated fragments,
   from Florian Westphal.

2) Fix Incorrect check for missing attribute in nft_osf.

3) Missing INT_MIN & INT_MAX definition for netfilter bridge uapi
   header, from Jiri Slaby.

4) Revert map lookup in nft_numgen, this is already possible with
   the existing infrastructure without this extension.

5) Fix wrong listing of set reference counter, make counter
   synchronous again, from Stefano Brivio.

6) Fix CIDR 0 in hash:net,port,net, from Eric Westbrook.

7) Fix allocation failure with large set, use kvcalloc().
   From Andrey Ryabinin.

8) No need to disable BH when fetch ip set comment, patch from
   Jozsef Kadlecsik.

9) Sanity check for valid sysfs entry in xt_IDLETIMER, from
   Taehee Yoo.

10) Fix suspicious rcu usage via ip_set() macro at netlink dump,
    from Jozsef Kadlecsik.

11) Fix setting default timeout via nfnetlink_cttimeout, this
    comes with preparation patch to add nf_{tcp,udp,...}_pernet()
    helper.

12) Allow ebtables table nat to be of filter type via nft_compat.
    From Florian Westphal.

13) Incorrect calculation of next bucket in early_drop, do no bump
    hash value, update bucket counter instead. From Vasily Khoruzhick.
