msm: mdss: Signal the fences when there is a dma_done timeout

During kickoff before proceeding with the configuration
for the current frame, we wait for the previous dma_done
to complete. If there is a dma_done timeout during the
kickoff, we are not proceeding with the current request and
hence the fences should be signaled before returning.
