pnfs: Automatically select blocks & objects layouts
Just like files-layout, blocks & objects layouts are part of the NFS 4.1 protocol and should be automatically selected if NFS_4_1 is selected. The small problem is that these depend on other Kernel support being present, while files only depends on NFS itself. This patch removes from the user choice the presence of objects and blocks layout. But makes sure these are selected only if the depended subsystems are present in the Kernel.
