From: Pablo Neira Ayuso <pablo@netfilter.org>

commit 271c5ca826e0c3c53e0eb4032f8eaedea1ee391c upstream.

While looping to build the bitmap of used anonymous set names, check the
current set in the iteration, instead of the one that is being created.

Fixes: 37a9cc525525 ("netfilter: nf_tables: add generation mask to sets")
