The websock code will create a GSource for tracking completion of the
handshake process, passing a QIOTask which is freed by the callback
when it completes, which means when a source is cancelled, nothing is
free'ing the task.

Switch to provide a data free callback to the GSource, which ensures
the QIOTask is always freed even when the main event callback never
fires.
