From: Michael Guralnik <michaelgur@xxxxxxxxxx>
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.
Fixes: 74b30b3ad5ce ("RDMA/mlx5: Set local port to one when accessing counters")
