ASoC: SOF: clarify use of widget complete flag

Browse source 
Currently, the complete flag is used only for the snd_soc_dapm_scheduler
type widgets to indicate that the pipeline has been set up. All other
widgets do not need it. Add a comment to clarify its usage and set the
complete flag to false only for the scheduler widget in
sof_widget_free().
