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).
