msm: mdss: notify frame done for wifi display kickoff without buffer

Browse source 
The frame done notification is required even for kickoff without
output buffer. This happens for pan-display path, where a kickoff
can be triggered without output buffer queueing first. By notifying
the frame done event, it allows the client to release retire fence
properly.
