Sebastiaan van Stijn e9185f10cf Don't log error if file is already closed ...

When closing the log-file, and the file is already
closed, there's no need to log an error.

This patch adds a `closed` boolean to check if the
file was closed, and if so, skip closing the file.
This prevents errors like this being logged:

    level=error msg="Error closing logger: invalid argument"
