At dongle unplug, dp initializes audio_comp followed by sending disconnect
event notification to audio and to make sure audio had shutdown completely
by wait for audio completion notification at display_disable(). This patch
will not re initialize audio_comp at display_disable() if audio shutdown
is triggered by dongle unplugged.
