ALSA: usb-audio: Add mute TLV for playback volumes on RODE NT-USB

BugLink: https://bugs.launchpad.net/bugs/1971496
commit 0f306cca42fe879694fb5e2382748c43dc9e0196 upstream.

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.
