In case of errors, dump the stats from history instead of using nstat. There are multiple advantages to that:
- The same filters from pr_err_stats are used, e.g. the unused 'rate' column is not displayed. - The counters are closer to the ones from when the test stopped. - While at it, the errors can be better presented: error colours, a small indentation to distinguish the different parts, extra new lines. Even if it should only happen in rare cases -- internal errors, or netns issues -- if no history is available, 'nstat' is used like before, just in case.
