Summary
With real UE, stateless MME is crashing while reading the protocol configuration options from Redis as there is no memory allocated in PDN context. While making this fix, also removed duplicate function for freeing pdn_context for each UE.
Test Plan
--- Set AGW to stateless mode
--- Attach UE to AGW
--- Restart MME service on AGW and confirm that there is no Segmentation fault while restarting
--- Detach UE and stop the MME service to verify there is no memory leak from this change
