Possible crash when receiving a CIP service request when in out of resources state

The device crashes when no more resources are available to serve a new CIP service request from DPM application (e.g. request sent too frequently, outstanding requests exist).

In the error path the CIP response data length is not set properly, resulting in undefined data length and invalid memory access.

Note: This is very unlikely to occur since an application typically sends a request and waits for the confirmation before sending the next request.
