tipc_ref_acquire - create reference to an object

Register an object pointer in reference table and lock the object. Returns a unique reference value that is used from then on to retrieve the object pointer, or to determine that the object has been deregistered.

Note: The object is returned in the locked state so that the caller can register a partially initialized object, without running the risk that the object will be accessed before initialization is complete.
