>prior to this change, since we ignored handshake msg, does that mean the connection fails when the peer sends a key_update?

Yes, that is correct
>since this change requires a kernel patch; what happens if the kernel patch is NOT applied but ktls is enabled?

KTLS will be used until key_update is received or send, after that it will be disabled and GnuTLS will fallback to default i.e. gnutls will handle encryption and decryption
