ALSA: usb-audio: move mixer_quirks' min_mute into common quirk

We have found more and more devices that have the same problem, that
the mixer's minimum value is muted. Accroding to pipewire's MR[1]
and Arch Linux wiki[2], this should be a very common problem in USB
audio devices. Move the quirk into common quirk,as a preparation of
more devices' quirk's patch coming on the road[3].

2. https://wiki.archlinux.org/index.php?title=PipeWire&oldid=804138#No_sound_from_USB_DAC_until_30%_volume
3. On the road, in the physical sense. We have been buying ton of
   these devices for testing the problem.
