ALSA: hda/cirrus: Fix CS42L42 Headset Mic volume control name

Existing name "Headset Mic Volume Control" causes multiple Microphone
entries to appear in UI. Using name "Mic Volume Control" ensures only a
single Microphone entry exists when the Headset is connected.

Tested on DELL Inspiron-3505, DELL Inspiron-3501, DELL Inspiron-3500
