Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) br_netfilter drops IPv6 packets if ipv6 is disabled, from Leonardo Bras.

2) nft_socket hits BUG() due to illegal skb->sk caching, patch from
   Fernando Fernandez Mancera.

3) nft_fib_netdev could be called with ipv6 disabled, leading to crash
   in the fib lookup, also from Leonardo.

4) ctnetlink honors IPS_OFFLOAD flag, just like nf_conntrack sysctl does.

5) Properly set up flowtable entry timeout, otherwise immediate
   removal by garbage collector might occur.
