[PATCH v3 1/1] net/mlx5: fix port down in link detection error branch

[Yang Xu]

The port down state was not initialized in the error branch
when detecting MLX NIC link status. This resulted in incorrect
link state reporting, as the device failed to reflect the actual
down status under error conditions.
