description:
HTTP/2: close connections initialized during graceful shutdown.

In some rare cases, graceful shutdown may happen while initializing an HTTP/2
connection. Previously, such a connection ignored the shutdown and remained
active. Now it is gracefully closed prior to processing any streams to
eliminate the shutdown delay.
