net/tls: remove old exports of sk_destruct functions
tls_device_sk_destruct being set on a socket used to indicate
that socket is a kTLS device one. That is no longer true -
now we use sk_validate_xmit_skb pointer for that purpose.
Remove the export. tls_device_attach() needs to be moved.
While at it, remove the dead declaration of tls_sk_destruct().
