Netfilter -stable patches for 6.1.y

Hi Greg, Sasha,

Could you please cherry-pick:

29ad9a305943 ("netfilter: nf_tables: fix underflow in chain reference counter") b8ae60de6fd3 ("netfilter: nf_tables: fix underflow in object reference counter"

into 6.1.y?

Other -stable kernels I have just audited do not need these updates, since this fix have been already included in my recent -stable backports.

Thanks.

P.S: Moving forward, I will add the Cc: stable@vger.kernel.org tag to patches as Greg suggested.
