ALSA: usb-audio: correct M-Audio C400 clock source quirk
Taking another look at the C400 descriptors, I see now that there is a clock selector (0x80) for this device. Right now, the clock source points to the internal clock (0x81), which is also valid. When the external clock source (0x82) is selected in the mixer, and the rates mismatch (if it's free-running it is fixed to 48KHz), xruns will occur. Set the clock ID to the clock selector unit (0x81), which then allows the validation code to function correctly.
