fix test_api negative_set_read_write_image_arg (#812)

clSetKernelArg is supposed to fail with CL_INVALID_ARG_VALUE when an image is created with CL_MEM_READ_ONLY is passed to a write_only kernel argument! (Got CL_SUCCESS, expected CL_INVALID_ARG_VALUE from <OpenCL-CTS>/test_conformance/api/test_kernels.cpp:842)
