ALSA: hda/generic - Don't override power_filter when power_save_node is set
Currently the generic parser sets codec->power_filter when power_save_node flag is set. But this overrides the existing filter that has been already set by the codec driver, thus it looses some features. Instead, set the default power_filter only when it's not set yet.
