wpa_supplicant: Cancel sched_scan when stopping countermeasures

When stopping the TKIP countermeasures, it would be preferable to
connect immediately. However if scheduled scan is in progress,
a connection attempt will be done only when scan results are received,
so cancel the scheduled scan to allow immediate scan and connection
attempt.
