[ 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.
