ALSA: hda - Fix mute-LED fixed mode

commit ee52e56e7b12834476cd0031c5986254ba1b6317 upstream.

The mute-LED mode control has the fixed on/off states that are
supposed to remain on/off regardless of the master switch.  However,
this doesn't work actually because the vmaster hook is called in the
vmaster code itself.

This patch fixes it by calling the hook indirectly after checking the
mute LED mode.
