重现Bug的步骤(How to replay bug?)
obs 推流： rtmp://172.24.0.75:1935/live/livestream

vlc拉流： http://172.24.0.75:9080/live/livestream.m3u8
可以拉流成功，正常观看

获取拉流客户端信息，然后API踢流 DELETE http://172.24.0.75:1985/api/v1/clients/o7zw2527
返回 "code": 400

但是同样的推流，
vlc用rmtp://172.24.0.75:1935/live/livestream拉流，就可以用API踢流成功
vlc用 http://172.24.0.75:9080/live/livestream.flv拉流，也可以API踢流成功

请问是srs不支持hls API踢流吗，还是别的原因呢

期望行为(Expect)

期望api可以hls踢流
