Subject: ALSA: usb-audio: Add sample rate inquiry quirk for AudioQuest DragonFly

From: Anssi Hannula <[email protected]>

commit 12a6116e66695a728bcb9616416c508ce9c051a1 upstream.

Avoid getting sample rate on AudioQuest DragonFly as it is unsupported and causes noisy "cannot get freq at ep 0x1" messages when playback starts.
