[PATCH] knfsd: Provide missing NFSv2 part of patch for checking vfs_getattr.

Browse source 
A recent patch which checked the return status of vfs_getattr in nfsd,
completely missed the nfsproc.c (NFSv2) part.  Here is it.

This patch moved the call to vfs_getattr from the xdr encoding (at which point
it is too late to return an error) to the call handling.  This means several
calls to vfs_getattr are needed in nfsproc.c.  Many are encapsulated in
nfsd_return_attrs and nfsd_return_dirop.
