ALSA: usb-audio: Add mute TLV for playback volumes on RODE NT-USB
For the RODE NT-USB the lowest Playback mixer volume setting mutes the audio output. But it is not reported as such causing e.g. PulseAudio to accidentally mute the device when selecting a low volume. Fix this by applying the existing quirk for this kind of issue when the device is detected.
