While starting from PNO start context, the scheduled scan was not setting the flag wpa_s->scanning. This was resulting in the subsequent SCAN command to proceed further and send command to nl80211/cfg80211. The expected behavior of cancelling sched_scan was not happening here. While sched_scan is in progress and a legacy scan comes on the cli/socket, the sched_scan is cancelled and normal scan is allowed to continue. However, sometimes sched_scan cancelled event comes a bit delayed and we will send out the scan command before the wpa_s->scanning is cleared. Instead, reschedule the incoming scan req if the wpa_s->scanning shows that it is still in progress. Signed-hostap: Jithu Jance <jithu@broadcom.com>
