Fix consumer stuck issue due to reuse entry wrapper. (apache#10824)
Fixes apache#10813 The issue is introduced by apache#7266, it only affects the master branch. ### Motivation 1. Add wrapperOffset to make sure get the correct batch size from the metadata 2. Fix the issue that using (batch count / avgBatchSizePerMsg) to calculate messages for the consumer it should be (messages / avgBatchSizePerMsg) ### Verifying this change * The test case is to simulate dispatch batches with different batch size to the consumer. * 1. The consumer has 1000 available permits * 2. The producer send batches with different batch size * * According the batch average size dispatching, the broker will dispatch all the batches to the consumer
