        WebCL Exception Error Code mismatch with OpenCL Codes.
        Issue #267

        Reviewed by Antonio.

        Currently the error codes are lagging from OpenCL codes by 1.
        The enum in  WebCLException must start from 1 rather than 0 to Map with OpenCL
        enum starting with -1.

        This was partially fixed by commit 88de014b2a8a7de6cf8b9ddeca74537308229390.
        But they was a mismatch in between OpenCL and WebCL codes due to above reason.

        No new tests (OOPS!).
