Since LISTEN is (still) disallowed, UNLISTEN must be a no-op in a hot-standby session, and so there's no harm in allowing it. This change allows client code to not worry about whether it's connected to a primary or standby server when performing session-state-reset type activities. (Note that DISCARD ALL, which includes UNLISTEN, was already allowed, making it inconsistent to reject UNLISTEN.) Per discussion, back-patch to all supported versions.
