Subject: [PATCH 3/7] ALSA: hda - use dell_micmute_led_set() instead of dell_app_wmi_led_set()

When the dell_app_wmi_led_set() method was introduced in db6d8cc
("dell-led: add mic mute led interface"), it was implemented as an
easily extensible entry point for other modules to set the state of
various LEDs.  However, almost three years later it is still only used
to control the mic mute LED, so it will be replaced with direct calls to
dell_micmute_led_set().
