Subject: [PATCH] HID: quirks: add NOGET quirk for Logitech GROUP

Add HID_QUIRK_NOGET for Logitech GROUP device.

Logitech GROUP is a compound with camera and audio.
When the HID interface in an audio device is requested to get
specific report id, all following control transfers are stalled
and never be restored back.
