Initializes descriptor for inner product weights gradient primitive.

@note Memory descriptors can be initialized with #dnnl_format_tag_any or with format_kind set to #dnnl_format_kind_any.

@param ip_desc Output descriptor for inner product primitive. @param src_desc Source memory descriptor. @param diff_weights_desc Diff weights memory descriptor. @param diff_bias_desc Diff bias memory descriptor. Passing NULL, a zero memory descriptor, or a memory descriptor with format_kind set to #dnnl_format_kind_undef disables the bias term. @param diff_dst_desc Diff destination memory descriptor. @returns #dnnl_success on success and a status describing the error otherwise.
