Sukchan Lee cd76dc641d [SEC] Crash and Protocol Violations 
The AMF will crash on the following locations when it receives a sequence
of NAS messages from a UE.

- ogs_nas_encrypt: Assertion `pkbuf->len' failed. (../lib/nas/common/security.c:86)
- gmm_state_authentication: Assertion `r != OGS_ERROR' failed. (../src/amf/gmm-sm.c:1561)

Besides the crashes found above, an incorrect protocol transition
is identified in Open5GS. Without any Registration/Attach Request message,
when the Identity Response message sent, the Core Network responds
with an Authentication Request message. According to the standard,
only the Registration/Attach Request message can start a state transition
from the 5GMM/EMM-DEREGISTERED state to the 5GMM/EMM-COMMON-PROCEDURE-INITIATED.

So I've modified the relevant code to address these issues.
