[pnfs] [PATCH] update file layout for draft 10 on the server side

[Ricardo Labiaga]

Hi Marc, Andy,

This update causes the XDR stream to contain 4 extra bytes of garbage
when 2 or more Data Servers are included in the layout.  The client
then incorrectly decodes a bogus device id.

The fix is to reduce the length by 4.  I'll send the patch separately.
