4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Florian Westphal <f...@strlen.de>


[ Upstream commit 4c82fd0abb87e20d0d68ef5237e74732352806c8 ]

nft_ct exposes this bit to userspace.  This used to be

  #define NF_CT_STATE_UNTRACKED_BIT              (1 << (IP_CT_NUMBER + 1))
  (IP_CT_NUMBER is 5, so this was 0x40)

.. but this got changed to 8 (0x100) when the untracked object got removed.
Replace this with a literal 6 to prevent further incompatible changes
in case IP_CT_NUMBER ever increases.

Fixes: cc41c84b7e7f2 ("netfilter: kill the fake untracked conntrack objects")
