Description
ssh_kdf() returns a success code on certain failures for libssh built with OpenSSL < 3.0

SSH_OK (0). Returning success code from the ssh_kdf() function without
initializing the output buffers can lead to use of uninitialized cryptographic
keys and failing to encrypt/decrypt following communication
