Because there is no `enb_ue` context.

to prevent retransmission of NAS messages.

herlesupreeth 4d6692d8fe fix: DRB lost issue when additional TFTs needs to be added to existing bearer with TFTs
This commit address the issue where a bearer with particular
PCC rule name exists with TFTs and addtional TFTs needs to be added
to same bearer and DRB lost is reported by UE.

This is achieved by creating EPS Bearer Level Traffic Flow Template
with TFT operation code as 'OGS_GTP_TFT_CODE_ADD_PACKET_FILTERS_TO_EXISTING_TFT' in
above scenario rather than use 'OGS_GTP_TFT_CODE_CREATE_NEW_TFT' at all times.
And, not remove existing packet filters for the bearer.

Sukchan Lee cc03c91bdd [AMF] 5G-GUTI generation changed (#910)
The AMF shall assign a new 5G-GUTI for a particular UE:
a) during  a successful initial registration procedure;
b) during a successful registration procedure
   for mobility registration update; and
c) after a successful service request procedure invoked as a response
   to a paging request from the network and before the release
   of the N1 NAS signalling connection as specified in subclause 5.4.4.1.

The AMF should assign a new 5G-GUTI for a particular UE
during a successful registration procedure
for periodic registration update. The AMF may assign a new 5G-GUTI
at any time for a particular UE by performing
the generic UE configuration update procedure.

Sukchan Lee 905fc76faf [AMF] Add NGAP ErrorIndication [#910]
1. UE sends PDU session establishment request to the AMF.
2. AMF initiates Release Due to Duplicate Session ID.
3. SMF cannot find the session by SM-Context-Ref.

For the above condition, AMF sends NGAP ErrorIndication to the UE.

Sukchan Lee b22023afb8 fix: creating allowed NSSAI (#859)
AMF checks whether it can serve all the S-NSSAI(s) from
the Requested NSSAI present in the Subscribed S-NSSAIs
(potentially using configuration for mapping S-NSSAI values
between HPLMN and Serving PLMN), or all the S-NSSAI(s) marked
as default in the Subscribed S-NSSAIs in the case that
no Requested NSSAI was provided or none of the S-NSSAIs
in the Requested NSSAI are permitted,
i.e. do not match any of the Subscribed S-NSSAIs or not available
at the current UE's Tracking Area (see clause 5.15.3).
