ALSA: usb-audio: support partially write-protected UAC2 controls
So far, UAC2 controls are marked read-only if any of the channels are
marked read-only in the descriptors. Change this behaviour and
- mark them writeable unless all channels are read-only
- store the read-only mask in usb_mixer_elem_info and
- check the mask again in set_cur_mix_value(), and bail out for
write-protected channels.
