When reusing a connection, the `host` and `conn_to_host` hostname structs are moved from the template connection onto the existing one. There was a NULLing of a tempplate member missing in `conn_to_host` which could then lead to a double free. Make this struct move into a static function, doing the correct thing for both `struct hostname` in a connection. reported-by: Joshua Rogers
