Description

In reference to comment https://github.com/apache/kafka/pull/16969#discussion_r1750754052 and https://github.com/apache/kafka/pull/17380#issuecomment-2401324630 , we need to refactor code between SharePartitionManager and DelayedShareFetch so that the initialization error of share partition gets considered.

Also, If a sharePartition is being initialized, any pending shareFetchRequest is blocked in the purgatory. So, after the initialization completes, we need to trigger a check in the share fetch purgatory to wake up pending delayed operations.
