Gardening: Remove unnecessary FIXME from GeoNotifier

Gardening: Remove unnecessary FIXME from GeoNotifier

GeoNotifier is managed in Geolocation and it's only used in Geolocation
and GeolocationWatcher which is also managed in Geolocation.
Therefore m_geolocation in GeoNotifier is not a problem
because there is no possibility to be used without Geolocation.
