Netfilter/IPVS fixes for net

The following patchset contains Netfilter/IPVS fixes for your net tree,
they are:

1) Validate hooks for nf_tables NAT expressions, otherwise users can
   crash the kernel when using them from the wrong hook. We already
   got one user trapped on this when configuring masquerading.

2) Fix a BUG splat in nf_tables with CONFIG_DEBUG_PREEMPT=y. Reported
   by Andreas Schultz.

3) Avoid unnecessary reroute of traffic in the local input path
   in IPVS that triggers a crash in in xfrm. Reported by Florian
   Wiessner and fixes by Julian Anastasov.

4) Fix memory and module refcount leak from the error path of
   nf_tables_newchain().
