disp: msm: sde: dma fence out of order handling in fence error case

Browse Source 
Handle out of order dma fence signalling and propagation of fence
error. Out of order fence signaling is required only in Video mode.
For example, in case of N, N+1, N+2 frames where N, N+2 are good
frames and N+1 is frame with fence error. The release fence signal
sequence in video mode would be N+1, N, N+2.
