Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Add NFT_CHAIN_POLICY_UNSET to replace hardcoded -1 to
   specify that the chain policy is unset. The chain policy
   field is actually defined as an 8-bit unsigned integer.

2) Remove always true condition reported by smatch in
   chain policy check.

3) Fix element lookup on dynamic sets, from Florian Westphal.

4) Use __u8 in ebtables uapi header, from Masahiro Yamada.

5) Bogus EBUSY when removing flowtable after chain flush,
   from Laura Garcia Liebana.
