What problem does this PR solve?
Fix the bug that region errors can be lost.
Issue Number: close #9673
What is changed and how it works?
Every region worker consumes region events from a queue. In
sharedRegionWorker.handleSingleRegionError, it clears the Region State from the source stream directly. It's wrong because the event can be a stale one and the Region State in the stream may be created after the region error is handled.This PR fixes the problem.

Will it cause performance regression or break compatibility?
Do you need to update user documentation, design documentation or monitoring documentation?
