Zhigang Gong 2e49ca4903 Avoid unmap an umat(ocl) which hasn't been mapped at all. 
According to opencl 1.2 spec 5.4.2:
  enqueues a command to unmap a previously mapped region of a memory object.
  ...
  CL_INVALID_VALUE if mapped_ptr is not a valid pointer returned by
  clEnqueueMapBuffer, or clEnqueueMapImage for memobj.

So if the u->data is not from a clEnqueueMapBuffer call, we should not
call clEnqueueUnmapMemObject() unmap it. With this patch, the cases
./opencv_test_video --gtest_filter=OCL_Video/FarnebackOpticalFlow.Mat/*
could work well with beignet 0.9.1, Otherwise, it will get a
CL_INVALID_VALUE at the clEnqueueUnmapMemObject().
