prestera_flower_prio_get() looks up the ruleset with prestera_acl_ruleset_lookup(), which increments its reference count, but returns without calling prestera_acl_ruleset_put(). The ruleset reference is leaked on every successful priority query. Release it after the priority range has been copied out.
