Isuue #875 clarified that CL_INVALID_BUFFER_SIZE should be returned if clCreateBuffer is passed a pointer returned by clSVMAlloc as its host_ptr and the size of the buffer exceeds the size of the SVM allocation. Add a new negative test to ensure CL_INVALID_BUFFER_SIZE is returned when the size of buffer exceeds the size of the SVM allocation. Fixes #1701
