Subject: [PATCH] Fix: decrease loglevel when unable to resolve addr

Upstream PR: https://github.com/saltstack/salt/pull/46575

It occurs that when the machine has multiple interfaces without an associated FQDN, Salt logs are polluted by this error.
Some examples:

```
caasp-admin:~ # uptime
 09:08am  up   0:13,  2 users,  load average: 1.30, 1.37, 0.98
caasp-admin:~ # docker logs $(docker ps | grep salt-master | awk '{print $1}') 2>&1 | grep "Exception during resolving address" | wc -l
528
```

```
caasp-admin:~ # docker exec -it $(docker ps | grep salt-master | awk '{print $1}') salt '*' cmd.run uptime

This patch changes the log level of the exception to INFO, since the resolve-unable problem is not blocking.
