HTTP/2: handling of connections initialized during shutdown.
If an HTTP/2 connection opened before a graceful shutdown, but
ngx_http_v2_init() is called after idle connections were closed, such
a connection ended up being open till closed by the client (or up to
keepalive_time), delaying shutdown.
With this change, such connections are allowed to serve just one request,
much like it happens in HTTP/1.x, and closed afterwards.
