[PATCH] wpa_supplicant: don't save prev_sched_ssid if not needed

[David Spinadel]

From: David Spinadel <david.spinadel at intel.com>

If the whole ssid list was scanned, don't save the prev
sheduled ssid since we are going to start from beggining.
It avoids starting sched scan from prev_sched_ssid after
scanning the full list, in case of adding network to ssid
during scheduled scan.
