netfilter: nft_dynset: dump expressions when set definition contains no expressions
If the set definition provides no stateful expressions, then include the stateful expression in the ruleset listing. Without this fix, the dynset rule listing shows the stateful expressions provided by the set definition. Fixes: 65038428b2c6 ("netfilter: nf_tables: allow to specify stateful expression in set definition") Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
