CA-114985: Fixed the issue where an empty summary page was displayed after creating Hardware HBA SR

- The problem was the Summary page was displayed before the lists of succeeded and failed actions have been populated (on the Completed event of each action).
- To fix it, we populate these lists after all the actions are completed, and on the event thread.
