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.
