[PR] [fix] [broker] Fix NPE which will leading dispatching stuck when using Key_Shared mode and set allowOutOfOrderDelivery to true [pulsar]

poorbarcode opened a new pull request, #22533:
URL: https://github.com/apache/pulsar/pull/22533

   ### Motivation
   
   In Key_Shared mode, the variable `recentlyJoinedConsumers` of `PersistentStickyKeyDispatcherMultipleConsumers` will always be null when enabling the config below.  #22245 introduced a NPE if set `allowOutOfOrderDelivery` to true, which will lead dispatching stuck.
   ```
   // The default value is false.
   pulsarClient.newConsumer().keySharedPolicy(KeySharedPolicy.setAllowOutOfOrderDelivery(true))
   ```
   
   ### Modifications
   
   Fix the NPE.
