commit b1db244ffd041a49ecc9618e8feb6b5c1afcdaa7 upstream.
When deactivating the catch-all set element, check the state in the next generation that represents this transaction.
This bug uncovered after the recent removal of the element busy mark a2dd0233cbc4 ("netfilter: nf_tables: remove busy mark and gc batch API").
