CVE-2023-54035

netfilter: nf_tables: fix underflow in chain reference counter

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: fix underflow in chain reference counter

Set element addition error path decrements reference counter on chains
twice: once on element release and again via nft_data_release().

Then, d6b478666ffa ("netfilter: nf_tables: fix underflow in object
reference counter") incorrectly fixed this by removing the stateful
object reference count decrement.

Restore the stateful object decrement as in b91d90368837 ("netfilter:
nf_tables: fix leaking object reference count") and let
nft_data_release() decrement the chain reference counter, so this is
done only once.
