mlx5 networking PMD supports probing ethdev ports based
on LAG configured on Linux kernel level.
In such cases, a single IB device is created in the kernel
and mlx5 PMD configured the device through this IB device.
In order to recognize whether PMD will run over LAG device or not,
mlx5 PMD relied on IB device name.
This patch fixes mlx5 networking PMD logic to rely on
mlx5_os_is_device_bond() introduced in previous commit,
instead of relying solely on IB device name.
Fixes: 2e569a370395 ("net/mlx5: add VF LAG mode bonding device recognition")
