Test cluster with 2 osds, stop osd.0, if osd.1 report the pg stats during pg peering, mon will record pg state to 'peering',then stop osd.1, finally the pg state will stuck in 'stale+peering', which is unexpected. Let's wait_for_active() after stop osd.0. Signed-off-by: huangjun <huangjun@xsky.com>
