kernel:nft "Could not process rule: Device or resource busy" on
unreferenced chain

Bug description:
We see some nftables/netfilter problems after kernel upgrade from
5.15.0-1061-gke to 5.15.0-1067-gke.
Correct transaction with nft fails with "Error: Could not process rule:
Device or resource busy"
which usually means a deleted chain is referenced, but you can see it's not.
Full nft table dump + transaction + error is in the attached file.
This is logs from kubernetes CI, which started failing immediately after
mentioned kernel update.
