[fix](arrow-flight-sql) Fix return result from FE Arrow Flight server error
`0.0.0.0:xxx, connection refused` (#40002)
Fix: #36340
Introduced in: #34850
```
adbc_driver_manager.OperationalError: IO: [FlightSQL] connection error:
desc = "transport: Error while dialing: dial tcp 0.0.0.0:8029: connect:
connection refused" (Unavailable; DoGet: endpoint 0:
[uri:"grpc+tcp://0.0.0.0:8029"])
```
When query results are returned from FE Arrow Flight server, and Doris
FE and ADBC Client are not on the same machine, such as `show
tables;`, `show databases;`, the IP in FlightInfo returned by FE to the
client is wrong, and `0.0.0.0` is returned instead of the real IP of FE.
The client fails to pull the results from `0.0.0.0`.
No problem when query results are returned from BE Arrow Flight server,
such as the normal query statement `select * from xxx`.
