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.

Fixes: 47069594e67e ("tls: implement rekey for TLS1.3")
