What I did
Do not start counter-polling for queues with zero buffer profiles if create_only_config_db_buffers is enabled.
Why I did it
If create_only_config_db_buffers is enabled, counters will be polled only on queues with a buffer configured based on the hypothesis that a customer must configure a buffer profile before using the queue.
The system performance can be optimized by reducing the number of counter polled.
However, zero buffer profiles are configured on queues of inactive ports to reclaim unused buffers. Those queues are not used by customers. Hence, we do not need to start counter polling for queues with such buffer profiles configured.
How I verified it
Manual and regression test.
