Move the execution of RecordWrite() before the graphDriver Cleanup(). This addresses a longstanding issue that occurs when the Podman cleanup process is forcely terminated and on some occasions the termination happens after the Cleanup() but before the change is recorded. This causes that the next user is not notified about the change and will mount the container without the home directory below (the infamous /var/lib/containers/storage/overlay mount). Then when the next time the graphDriver is initialized, the home directory is mounted on top of the existing mounts causing some containers to fail with ENOENT since all files are hidden and some others cannot be cleaned up since their mount directory is covered by the home directory mount.
