BUG REPORT

1. Please describe the issue you observed:

   • What did you do (The steps to reproduce)?
     I disable write permission for a broker.

   • What did you expect to see?
     All queues belong to this broker are not allowed to write.

   • What did you see instead?
     queues belongs to topic RMQ_SYS_TRACE_TOPIC still emit messages to this broker.

I read trace.go code for a while and found that routeInfoData for topic RMQ_SYS_TRACE_TOPIC will never update since first boot;
Maybe we should add a timer to process UpdateTopicRouteInfo job every several seconds
