Fixed QAudioDeviceInfoInternal::deviceList(QAudio::Mode mode) filtering

If an audio device only supported Input or Output, it would not be added
to the list of devices. Only devices that returned IOID == NULL would be
added. Also, _m was not being used, and io was unneccessarily being cast
to a QString.
