Fix sched_scan for max-num-of-scan_ssid=1 networks

When the network configuration includes exactly the number of
scan_ssid=1 networks as the driver supports for scan_sched and no
networks need wildcard SSID scan, there is no need to use sched_scan
timeout. Check this condition and optimize this case to avoid the extra
sched_scan start/stop operations.
