URL: https://github.com/apache/doris/pull/61593

   - Change `_try_close` from `bool` to `std::atomic<bool>` with 
acquire/release memory ordering
   - Use `memory_order_acquire` when reading in `_send_batch_process()` 
(bthread)
   - Use `memory_order_release` when writing in `_do_try_close()` (pthread)
   - Remove unused `_close_wait` field
   
   This fixes a potential race condition where `_try_close` is written by 
pthread and read by bthread without proper synchronization.
   
   It's ok on x86 so no test added.
