netfilter: nf_tables: check if catch-all set element is active in next generation

Browse Source 
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").

Fixes: aaa31047a6d2 ("netfilter: nftables: add catch-all set element support")
