    Fix a lazy-load exception in security_group_update()

    When security_group_api is nova, the update_security_group api raises http
    500 error: group rules fails with lazy load exception. Because the rule
    infos of the security group will be return in response body, but the rule
    attribute hasn't been preloaded.
