Avoid notifying the FUSE daemon for invisible volumes

Browse Source 
Invisible volumes/USB OTG volumes are neither exposed to apps nor the
MediaStore. Calling into the FUSE daemon for invisible volumes can
lead to unexpected exceptions if the MediaProvider tries to get more
information about the StorageVolume from the StorageManagerService
