knfsd: demote some printk()s to dprintk()s
To quote a recent mail from Andrew Morton:
Look: if there's a way in which an unprivileged user can trigger
a printk we fix it, end of story.
OK. I assume that goes double for printk()s that might be triggered by
random hosts on the internet. So, disable some printk()s that look like
they could be triggered by malfunctioning or malicious clients. For
now, just downgrade them to dprintk()s.
