ALSA: usb-audio: ignore-quirk for HP Wireless Audio
As Joe Cooper <swelljoe@gmail.com> reported, "On most HP Envy laptops
the snd-usb-audio module causes the system to become unresponsive and
Gnome Shell 3 to crash.".

Add a quirk to ignore this device (for now) to solve the instability
issue and allow other USB audio devices to be used.
