UPSTREAM: netfilter: nf_tables: skip set commit for deleted/destroyed sets

commit 7315dc1e 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.
