fix the distortion issue in some 1080i interlace clips

BZ: 199433

1.ReferenceFrames have VA_PICTURE_H264_BOTTOM_FIELD set, which confuse
  VED to address top field.
2.H264 dpb is wrongly updated when libmix handle SEI recover_point.
3.Set the default poc as max of int32 to avoid reference frame missing
  issue when frame/field poc is -1.
