ALSA: hda: generic: Remove obsolete call to ledtrig_audio_get

Since 64f67b5 ("leds: trigger: audio: Add an activate callback to
ensure the initial brightness is set") the audio triggers have an
activate callback which sets the LED brightness as soon as the
(default) trigger is bound to the LED device. So we can remove the
call to ledtrig_audio_get.

Positive side effect: We have no code dependency to ledtrig-audio any
longer, therefore, if built as module, it's no longer loaded if not
needed.
