Currently, the NFS readdir decoders have a workaround for buggy servers that send an empty readdir response with the EOF bit unset. If the server sends a malformed response in some cases, this workaround kicks in and just returns an empty response rather than returning a proper error to the caller. This patch does 3 things: 1) have malformed responses with no entries return error (-EIO) 2) preserve existing workaround for servers that send empty responses with the EOF marker unset. 3) Add some comments to clarify the logic in nfs3_xdr_readdirres().
