Subject: [PATCH 4/5] nfs: Fix -o sec=none output in /proc/mounts

Linux nfs userspace tools supports AUTH_NULL flavor under name 'none'.
This name is used in /etc/exports file and also in '-o sec' mount option.

So for compatibility show AUTH_NULL flavor in /proc/mounts output as 'none'
instead of 'null'.
