Summary: **Context** https://github.com/facebook/rocksdb/pull/10348 allows multi-level FIFO but accidentally made change to the logic of deleting files in `FIFOCompactionPicker::PickSizeCompaction`. With [this](https://github.com/facebook/rocksdb/pull/10348/files#diff-d8fb3d50749aa69b378de447e3d9cf2f48abe0281437f010b5d61365a7b813fdR156) and [this](https://github.com/facebook/rocksdb/pull/10348/files#diff-d8fb3d50749aa69b378de447e3d9cf2f48abe0281437f010b5d61365a7b813fdR235) together, it deletes one file in non-L0 even when `total_size <= mutable_cf_options.compaction_options_fifo.max_table_files_size`, which is incorrect. As a consequence, FIFO exercises more file deletion in our crash testing, which is not able to verify correctly on deleted keys in the file deleted by compaction. This results in errors `error : inconsistent values for key 000000000000239F000000000000012B000000000000028B: expected state has the key, Get() returns NotFound.
