Subject: [PATCH] ALSA: usb-audio: Apply sample rate quirk to Logitech Connect

Logitech ConferenceCam Connect is a compound USB device with UVC and
UAC. Not 100% reproducible but sometimes it keeps responding STALL to
every control transfer once it receives get_freq request.

This patch adds 046d:0x084c to a snd_usb_get_sample_rate_quirk list.
