Sukchan Lee 8484a5af60 [GTP] Incorrect destination TEID=0 (#3043) 
If eg. PCRF or AAA diameter link is not yet ready (eg. PCRF crashed),
and a client sends a CreateSessionRequest announcing its ow F-TEID,
then open5gs-smfd answers with Create Session Response Cause=
"Remote peer not responding", but it is not setting the received F-TEID
in the header of the response, instead it sends with TEI=0.

As a result, the peer cannot match the CreateSessionResponse,
and needs to rely on its own timeout timer to figure out
that specific request failed.

To address this issue, I modified the GTP Response message to check
the Sender F-TEID and send it accordingly, setting the destination TEID
to the value of the Sender F-TEID.

I've made this modification only for SMF, but MME and SGW-C have not done so;
if you need to, you can work from the examples in SMF.

Similarly, the same situation can happen with PFCP. If anyone needs to do this
in the future, I think you can work on it this way.
