GstVaapiDeinterlaceState requires reset when there is discontinuity.
for example: the cached previous frame is not valid after seek.

    vaapipostproc: reset deinterlacer state when there is a discontinuity.
    
    Reset deinterlacer state, i.e. past reference frames used for advanced
    deinterlacing, when there is some discontinuity detected in the course
    of processing source buffers.
    
    This fixes support for advanced deinterlacing when a seek occurred.

    [fixed type of pts_diff variable, fetch previous buffer PTS from the
     history buffer, reduce heuristic for detecting discontinuity]
