Fix wake and scan behavior
- Add wakelock for driver start/stop to ensure a wifilock
acquisition kick starts driver. Also cleaned up state machine
driver start/stop behavior.
- Add periodic scans when driver is started to ensure wifi
reconnections when wifilock exists or when user chooses
never to sleep
- some minor clean up
