sta_scan_pending was supposed to be accurate enough for determining whether a P2P scan needs to be postponed. However, it has turned out that there were cases where sta_scan_pending was not cleared properly. While the known cases have now been addressed, it is possible that some other cases may still exist. To avoid issues with P2P operationg getting stuck, verify more carefully that there is a real pending station mode scan (either in progress or scheduled to be requested).
