Sukchan Lee 6f11a78079 If SCTP use SOCK_STREAM, Use BUFFERING method.
Most of the time, an application wants to perform some amount of data buffering
in addition to just responding to events. When we want to write data,
for example, the usual pattern runs something like:

1. Decide that we want to write some data to a connection;
   put that data in a buffer.
2. Wait for the connection to become writable
3. Write as much of the data as we can
4. Remember how much we wrote, and if we still have more data to write,
   wait for the connection to become writable again.

Now, Open5GS implements the above method by default when transmitting data
in a stream type socket.

Sukchan Lee d73ff77031 We cannot initialize the state in all cases. [#569]
In TS24.501 Ch 5.5.1.3.8 Abnormal cases on the network side

d) REGISTRATION REQUEST with 5GS registration type IE set to
"mobility registration updating" or "periodic registration updating"
received after the REGISTRATION ACCEPT message has been sent and
before the REGISTRATION COMPLETE message is received.

Since, we have to do this special case, it is desirable
to handle it directly inside the state(gmm-sm.c).
