Fix crash as server when resuming with SNI.
Thanks to Denis Denisov for noting that |host_name| could be used while
uninitialised in the resumption case.
While in the area, this change also renames |servername_done| to
something more reasonable and removes a documented value that was never
used. Additionally, the SNI ack was only sent when not resuming so
calculating whether it should be sent when processing ClientHello
extensions (which is after s->hit has been set) is superfluous.
Lastly, since SNI is only acked by servers, there's no need to worry
about the SNI callback returning NOACK in the client case.
