Initial Geolocation Wifi Scan Checking Fix for CrOS

Initial Geolocation Wifi Scan Checking Fix for CrOS

The ChromeOS Wifi provider was erronously reporting an initial
scan of 0 wifi access points when the shill's scanning had not
yet completed. This resulted in a fallback to IP geo for the
first request and then proper Wifi based location on the
second request.

Thanks for sending this for the review, but I'm not familiar with this code :)
I'd suggest continuing with the owners.
Thanks!
