[Beignet] opencv_test_imgproc crashs when test OCL_Imgproc/HoughLines.RealImage/0

[yan.wang at linux.intel.com]

I am not sure whether it is platform issue. So far I have only Baytail T
platform no others. The assertion will not be hit now. Still need me
submit bug? I could do it.

It may be the bug of OpenCL implementation of opecv hough lines for fail
case. Need more investigation.
