[PATCH nft 2/4] ct: refactor print function so it can be re-used for ct statement

[Pablo Neira Ayuso <pablo@netfilter.org>]

From: Florian Westphal <fw@strlen.de>

Once directional zone support is added we also need to print the
direction of the statement, so factor the common code to re-use
this helper from the statement print function.

Just a rebase on top of series to store byteorder for set data in
NFTA_SET_USERDATA.
