ALSA: usb-audio: apply quirk for Huawei Technologies Co., Ltd. CM-Q3

There're several different actual hardwares sold by Huawei, using the
same USB ID 12d1:3a07.

The first one we found, having a volume control named "Headset Playback
Volume", reports a min value -15360, and will mute iff setting it to
-15360. It can be simply fixed by quirk flag MIXER_PLAYBACK_MIN_MUTE,
which we have already submitted previously.[1]

The second one we found today, having a volume control named "PCM
Playback Volume", reports its min -11520 and res 256, and will mute
when less than -11008. Because of the already existing quirk flag, we
can just set its min to -11264, and the new minimum value will still
not be available to userspace, so that userspace's minimum will be the
correct -11008.
