ALSA: usb-audio: FIX native DSD support for TEAC UD-501 DAC
There are two versions of TEAC UD-501, the normal version and the vendor updated version(UD-501V2). They have the same VID/PID, but the num of the altsetting is different, UD-501 has 2 altsets for stream, and UD-501V2 has 3. So, add the logic to distinguish them by the Product Name, not by the PID.
