commit 0c5b7a501e7400869ee905b4f7af3d6717802bcb upstream.
Otherwise, the newly create element shows no timeout when listing the ruleset. If the set definition does not specify a default timeout, then the set element only shows the expiration time, but not the timeout. This is a problem when restoring a stateful ruleset listing since it skips the timeout policy entirely.
