[Llama3-8b-edge] Singlestream performnace mode samples

@arjunsuresh @pgmpablo157321 While giving a run of the singlestream performance mode, I noticed that the number of samples being run is much higher than the 5k that was designated by the taskforce. I'm tracking the number of samples being received and it's gone beyond even 10k.

The log details also has some weird values for the generated and effective min query count (I only used the default mlperf.conf parameters)

This is an unexpected behavior.
Below is the last processed queries I've tracked so far

Reproduce the Llama3-8b-edge singlestream performance mode with the default mlperf.conf and inspect the MLPerf LoadGen settings shown in the logs. Compare the configured 5,000 samples with effective_min_query_count and generated_query_count, then confirm that processing stops at the intended sample count.
