Issue: [Bug] It seems run wrong number of prompts when max-num-workers > 1. 
Root cause: Algorithmic Error

### Prerequisite

- [X] I have searched [Issues](https://github.com/open-compass/opencompass/issues/) and [Discussions](https://github.com/open-compass/opencompass/discussions) but cannot get the expected help.
- [X] The bug has not been fixed in the [latest version](https://github.com/open-compass/opencompass).

### Type

I'm evaluating with the officially supported tasks/models/datasets.

### Environment

### Reproduces the problem - code/configuration sample

opencompass --models hf_internlm2_5_7b --datasets race_ppl --max-num-workers 2 


I want to get race_ppl value (the dataset has 3000+ prompts), but only 100 prompts are inferenced. It seems run wrong number of prompts when max-num-workers > 1

### Reproduces the problem - command or script

opencompass --models hf_internlm2_5_7b --datasets race_ppl --max-num-workers 2
