During inspection of a packet trace, I noticed that an NFSv4.0 mount reported that it supported attributes that are only defined for NFSv4.1. In practice, this bug appears to be benign, since NFSv4.0 clients will not use attributes that were added for NFSv4.1. However, this was not correct and this patch fixes the NFSv4.0 server so that it only supports attributes defined for NFSv4.0. It also adds a definition for NFSv4.1 attributes that can only be set, although it is only defined as 0 for now. This is anticipation of the addition of support for the NFSv4.1 mode+mask attribute soon. MFC after: 2 weeks
