Windows: Fixed I/O bug in the CommOverlappedEventNotifier

This bug is a critical regression, which makes it impossible
to read the data as they become available because
CommOverlappedEventNotifier::processCompletionRoutine()
returns false if successful completed, i.e. returns a error flag
instead of inversion it.

Now, processCompletionRoutine() returns true if successful completion.
