Changyu Bi 2e8cc98ab2 Fix subcompaction bug to allow running two subcompactions (#11501) 
Summary:
as reported in https://github.com/facebook/rocksdb/issues/11476, RocksDB currently does not execute compactions in two subcompactions even when they qualify. This PR fixes this issue.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/11501

Test Plan:
* Add a new unit test.
* Run crash test with max_subcompactions=2: `python3 tools/db_crashtest.py blackbox --simple  --subcompactions=2 --target_file_size_base=1048576 --compaction_style=0`
  * saw logs showing compactions being executed as 2 subcompactions
```
