Incorrect parameter for UnsupportedRequest

[steven-bellock]

There are many instances of

libspdm/library/spdm_responder_lib/libspdm_rsp_heartbeat.c

Lines 25 to 29 in c0eaae4

	if (libspdm_get_connection_version(spdm_context) < SPDM_MESSAGE_VERSION_11) {
	return libspdm_generate_error_response(spdm_context,
	SPDM_ERROR_CODE_UNSUPPORTED_REQUEST, 0,
	response_size, response);
	}

where a value of 0 is given for the error data, rather than the RequestResponseCode in the request message.
