Subject: [PATCH] fix(caching): guard against None async_redis_conn_pool in
 RedisCache.disconnect

Fixes #31206

When REDIS_CLUSTER_NODES is set, get_redis_connection_pool() returns None
because the cluster mode path exits early. This causes RedisCache.__init__
to store self.async_redis_conn_pool = None. At shutdown, disconnect() then
crashes with AttributeError: 'NoneType' has no attribute 'disconnect'.

Add a None guard before calling .disconnect() on the connection pool.
