commit 64752a95b702817602d72f109ceaf5ec0780e283 upstream.
Recently we've added a new usb_mixer element type, USB_MIXER_BESPOKEN, but it wasn't added in the table in snd_usb_mixer_dump_cval(). This is no big problem since each bespoken type should have its own dump method, but it still isn't disallowed to use the standard one, so we should cover it as well. Along with it, define the table with the explicit array initializer for avoiding other pitfalls.
