disp: msm: dp: skip wait if audio engine is disabled

Browse Source 
Skip the wait in the disable path if the audio engine has already
been disabled or was not previously enabled. This avoids an
unnecessary wait since the audio subsystem will only acknowledge
the notification and not request a tear down if no audio playback
was started by the user.
