QtHttp: Lower the severity of some log output

The output was only printed if the request was no longer available
queued, meaning that it had been removed before the socket had finished
its connection attempt. That means the result of the attempt is not of
much interest to the user so we should not print it out as a warning.
The reason for why the request was removed from the queue would be the
interesting bit, but it's not covered here.
