Add delayed scheduled scan request
When initializing, the scheduled scan code was being called before everything is ready. With normal scans, the first scan round is delayed, so the initialization is finished by the time it really starts. Add a function that can be used to request a delayed scheduled scan. The scan will only start after the specified time has elapsed. Call this function instead of starting the scheduled scan directly during driver initialization.
