RDMA/mlx5: Fix port number for counter query in multi-port configuration
[ Upstream commit be121ffb384f53e966ee7299ffccc6eeb61bc73d ]
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")
