ALSA: usb-audio: Add MIN_MUTE quirk for Creative Sound Blaster Play! 3

Browse Source 
The Creative Sound Blaster Play! 3 (041e:324d) exposes a Feature Unit
volume control with a range of -44.00 dB .. 0.00 dB over raw values
0..88, but raw value 0 is in fact a hard mute rather than -44.00 dB.

Tested on hardware.
