Increase min sched_scan interval from 2 to 10 seconds

Trying to run sched_scan round every two seconds by defaults sounds way
too frequent since dualband cards are unlikely to be able to complete
the full scan cycle in two seconds. For now, set the hardcoded value to
10 seconds to make this somewhat more reasonable.
