[PFCP] Fix wrong endianess enc of some URR values (#1433) 
* [PFCP] Fix trailing whitespace

* [PFCP] Fix wrong endianess enc of some URR values

u32 tlvs are already converted to big endian automatically. Manually
doing so ends up in double conversion and hence in wrong endianness
being sent over the wire.
Similar issue was also fixed recently in the PFCP decoding path.

Sukchan Lee 13f1b390ae CVE-2021-41794 from NCC Group by Mark Tedman 
When connecting to the UPF port for the PFCP protocol (8805) and sending
an association setup request followed by a session establishment request
with a PDI Network Instance set to ‘internet’, it causes a stack corruption
to occur.

So, ogs_fqdn_parse() fixed.

Sukchan Lee 1bed0d5872 [#568] Add GTP-U Error Indication Handling 
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.
