…grpc#8646) Addresses a problem where we initially only resolve addresses to the backends, but not the load balancer and then later resolve addresses to both. In this situation the fallback timer was started during the second instance even if it resulted in the timer later failing as we were already using fallback backends. This change assures that a fallback time is only ever started if we are not already using the fallback backends. This is a follow-up fix to grpc#8253.
