I don't think this is right. Either we can just not call into the throttling
system if the request is not eligible for throttling, or we should pass along
the network delegate during URLRequestThrottlerManager::RegisterRequestUrl

     int num_failures = GetBackoffEntry()->failure_count();
     int release_after_ms =
         GetBackoffEntry()->GetTimeUntilRelease().InMilliseconds();
