tdeioslave/sftp: use realmValue to distinguish different prompts
This will help kpasswdserver not to confuse different user's answers to different questions. Also avoid passing/returning TDE::AuthInfo for kb-interactive auth as it isn't really necessary when we don't manually caching passwords anymore. Signed-off-by: Alexander Golubev <fatzer2@gmail.com>
