[fix] [broker] [branch-3.0] Fast fix infinite HTTP call createSubscri…

…ptions caused by wrong topicName (apache#21997)

Similar to: apache#20131

The master branch has fixed the issue by apache#19841 Since it will makes users can not receive the messages which created in mistake, we did not cherry-pick apache#19841 into other branches, see detail apache#19841)

It works like this:
1. createSubscription( `tp1` )
2. is partitioned topic?
  `no`: return subscriptions
  `yes`: createSubscription(`tp1-partition-0`)....createSubscription(`tp1-partition-n`)

---

```java
String partitionedTopic = "tp1-partition-0-DLQ";

TopicName partition0 = partitionedTopic.getPartition(0);// Highlight: the partition0.toString() will be "tp1-partition-0-DLQ"(it is wrong).The correct value is "tp1-partition-0-DLQ-partition-0"
```

Therefore, if there has a partitioned topic named `tp1-partition-0-DLQ`, the method `PersistentTopics.createSubscription` will works like this:
1. call Admin API ``PersistentTopics.createSubscription("tp1-partition-0-DLQ")`
2. is partitioned topic?
3. yes, call `TopicName.getPartition(0)` to get partition 0 and will get `tp1-partition-0-DLQ` , then loop to step-1.

Then the infinite HTTP call `PersistentTopics.createSubscription` makes the broker crash.

If hits the issue which makes the topic name wrong, do not loop to step 1.

The PR apache#19841 fixes the issue which makes the topic name wrong, and this PR will create unfriendly compatibility, and PIP 263 apache#20033 will make compatibility good.
