From: Olga Kornievskaia <kolga@xxxxxxxxxx>
Currently, even though xprtsec=tls is specified and used for operations
to MDS, any operations that go to DS travel over unencrypted connection.
IN GETDEVINCEINFO, we get an entry for the DS which carries a protocol
type (which is TCP), then nfs4_set_ds_client() gets called with TCP
instead of TCP with TLS.
Fixes: c8407f2e560c ("NFS: Add an "xprtsec=" NFS mount option")
