    gphoto2: Recognize cameras which don't implement get storageinfo
    
    Not all gphoto drivers implement get storage info (drivers for proprietary
    protocols often don't). This patch fixes the gphoto2volumemonitor to still
    recognize cams which gphoto driver does not implement get storage info.
