Subject: [PATCH] journal: Skip data objects with invalid offsets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We already skip invalid objects, but don't yet skip invalid offsets.
Let's skip these as well to improve robustness when we're dealing with
corrupted journals.

Before:

```
➜  systemd git:(main) build/journalctl -r -n 5 --file ~/Downloads/system@0005d2b275abaaf8-f243a2818cb39b98.journal_
Failed to get journal fields: Cannot assign requested address
-- No entries --
```

After:

```
➜  systemd git:(main) ✗ build/journalctl -r -n 5 --file ~/Downloads/system@0005d2b275abaaf8-f243a2818cb39b98.journal_

```
