net/mlx5: check kernel support for VF LAG bonding

Browse Source 
If bonding Infiniband device is found the unified E-Switch
is supposed and the extra rdma-core/kernel support is needed
to retrieve vport indices. The patch introduces this feature
defines, bonding support check is added to probe routine.
