### Motivation The `availablePermitsCh` may cause the dispatcher stuck. https://github.com/apache/pulsar-client-go/blob/0b0720ab73d7f6378b8b6ac37acbafe547c268c8/pulsar/consumer_partition.go#L1096-L1109 For example, if `messageCh <- nextMessage` continueously selected 10 times, the `availablePermitsCh` will be filled. The next `messageCh <- nextMessage` will be stuck forever because `pr := <-pc.availablePermitsCh` can never be reached. ### Modifications Move `<-pc.availablePermitsCh` before all the `pc.availablePermitsCh<-`. ### Verifying this change - [x] Make sure that the change passes the CI checks. *(Please pick either of the following options)* This change is a trivial rework / code cleanup without any test coverage. *(or)* This change is already covered by existing tests, such as *(please describe tests)*. *(or)* This change added tests and can be verified as follows: -- This is an automated message from the Apache Git Service.
