[Beignet] possilbe bug when run opencv_test_imgproc

[yan.wang at linux.intel.com]

Hi, Zhigang,
  May your platform also get failed cases when run
OCL_ImageProc/Filter2D.Mat* although no crash, because I have only
Baytail T platfrom. I am not sure the other platform has the same issue.
  If yes, I could try to investigate the reason. It may have issue of
filter2D OpenCL implementation in OpenCV.
  Thanks.

Yan Wang
