Describe the bug

When use 16DP+16EP，can't use profiler in sglang

Reproduction

start a 16DP+16EP instance, and use curl http://localhost:30000/start_profile -H "Content-Type: application/json" to start profiler, use curl http://localhost:30000/stop_profile -H "Content-Type: application/json" to stop prodiler
