Subject: netfilter: nf_tables: skip set commit for deleted/destroyed sets
From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>
commit 7315dc1e122c85ffdfc8defffbb8f8b616c2eb1a upstream.
NFT_MSG_DELSET deactivates all elements in the set, skip
set->ops->commit() to avoid the unnecessary clone (for the pipapo case)
as well as the sync GC cycle, which could deactivate again expired
elements in such set.
Fixes: 5f68718b34a5 ("netfilter: nf_tables: GC transaction API to avoid race with control plane")
