Allow concurrent normal scan and sched scan (UPSTREAM)
Some drivers support sched scan and normal scan. Enable this by configuration of concurrent_sched_scan=1 This can speed up connection to scan_ssid=1 networks as the sched scan doesn't get interrupted by a normal scan for wildcard SSID. Signed-off-by: Eyal Shapira <eyal@wizery.com>
