[ALSA] usb-audio: another Logitech QuickCam ID

This patch adds the ID for another quickcam microphone, reported by freqmod
on ALSA ticket #0003040
I'm going to submit a USB patch separately to provide a macro to simplify these
entries, as suggested by Alan Stern. We could switch to using that in future.
