Sabrina Dubroca 06cc878651 tls: skip setting sk_write_space on rekey ... syzbot reported a problem when calling setsockopt(SO_SNDBUF) after a rekey. SO_SNDBUF calls sk_write_space, ie tls_write_space, which then calls the original socket's sk_write_space, saved in ctx->sk_write_space. Rekeys should skip re-assigning ctx->sk_write_space, so we don't end up with tls_write_space calling itself.
