RDMA/mlx5: Fix port number for counter query in multi-port configuration

Browse Source 
Set the correct port when querying PPCNT in multi-port configuration.
Distinguish between cases where switchdev mode was enabled to multi-port
configuration and don't overwrite the queried port to 1 in multi-port
case.
