ASoC: SOF: sof-audio: Set up/free DAI/AIF widgets only once

Browse source 
Calling the sof_widget_setup/free() for the DAI/AIF widgets inside the
snd_soc_dapm_widget_for_each_sink_path() loop will end up setting up or
freeing the widget multiple times if there are multiple paths leaving
the widget. Fix this by moving the widget setup/free for the starting
widget in each path outside the loop.
