The open recovery code does not need to request a new value for the mdsthreshold, and so does not allocate a struct nfs4_threshold. The problem is that encode_getfattr_open() will still request an mdsthreshold, and so we end up Oopsing in decode_attr_mdsthreshold. This patch fixes encode_getfattr_open so that it doesn't request an mdsthreshold when the caller isn't asking for one. It also fixes decode_attr_mdsthreshold so that it errors if the server returns an mdsthreshold that we didn't ask for (instead of Oopsing).
