4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paolo Abeni <pabeni@xxxxxxxxxx>
[ Upstream commit cb20f2d2c0507d60d94ef896991e95708f051dd1 ]
The commit 2eb0f624b709 ("netfilter: add NAT support for shifted
portmap ranges") did not set the checkentry/destroy callbacks for
the newly added DNAT target. As a result, rulesets using only
such nat targets are not effective, as the relevant conntrack hooks
are not enabled.
The above affect also nft_compat rulesets.
Fix the issue adding the missing initializers.
