[SMF] Fix potential null pointer dereference (#1324) 
* [SMF] Fix potential null pointer dereference

Pointer "sess" was first dereferenced and later on checked for nullness.
This is clearly wrong. Rearrange the code path to make sure the check is
done first, then dereferenced.

* gitignore: Add subprojects/libtins

* cosmetic: Fix whitespace

Sukchan Lee 79239d8eff [IMPORTANT] changed network_access_mode: 0 (#1323) 
The network access mode of HSS has been changed to 0 (Packet and Circuit).

Versions of MME prior to v2.4.2 did not use this value. Open5GS set
the attach result of Attach Complete message as it is by looking
at the attach type of the Attach Request message.

Now, if the network access mode of HSS is set to 2 (Only Packet),
this value is affected by MME from v2.4.3. Regardless of the attach type
of the Attach Request, the MME will set EPS Only to the attach result
of Attach Complete.

[SMF] Fix router advertisement as per rfc 4861 (#1291) 
As per RFC 4861 Router advertisement message
format, Source Address MUST be the link-local address
assigned to the interface from which this message is sent.

Since SMF was not sending it as per RFC, certain
phones were not completing the procedure of stateless
IPv6 address autoconfiguration mentioned in
3GPP TS 23.401 version 15.12.0 Release 15, section 5.3.1.2.2

Sukchan Lee aab8286401 [MME] fix the crash issue if enb_ue is NULL(#1275) 
An assert occurs when a NAS message retransmission occurs.

Because there is no `enb_ue` context.

Therefore, before removing enb_ue, all Timers must be stopped
to prevent retransmission of NAS messages.
