1. SCTP event size workaround - stolen code from libosmo-netif
2. Remove PFCP User Plane IP resource information
3. Fix the bug when building Initial Context Setup Request with EMM NAS message.
So far, no operation was performed when Error Indication was received
from eNodeB. For that reason, I solved #568 issues by controlling
the MME to prevent this from happening.
Now, when GTP-U Error Indication is received, MME and SGW are implemented
to do what they have to do. I hope that the network can be restored
by responding appropriately even if Error Indication occurs.

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).
