Fix scan rescheduling from wpas_stop_pno to check postponed case

Browse Source 
Commit 02e122a995dea947a2ad2c0d85190d709f9128b7 ('Reschedule scan from
wpas_stop_pno if it was postponed') uses wpa_s->scanning as the only
condition for automatically starting a postponed scan request from
EVENT_SCHED_SCAN_STOPPED event handler. However, wpa_s->scanning may be
set for sched_scan and as such, this can result in unexpected extra
scans without there having been any real postponed request.

Make this more accurate by verifying that there really is a pending
request for a scan before speeding up its start.
