[tls] Keep cipherstream window open until TLS negotiation is complete
When performing a SAN boot, the plainstream window size will be zero
(since this is the mechanism used internally to indicate that no data
should be fetched via the initial request). This zero value currently
propagates to the advertised TCP window size, which prevents the TLS
negotiation from completing.
Fix by ensuring that the cipherstream window is held open until TLS
negotiation is complete, and only then falling back to passing through
the plainstream window size.
