net/mlx5: Use reversed order when unregister devices
When lag is active, which is controlled by the bonded mlx5e netdev, mlx5 interface unregestering must happen in the reverse order where rdma is unregistered (unloaded) first, to guarantee all references to the lag context in hardware is removed, then remove mlx5e netdev interface which will cleanup the lag context from hardware. Without this fix during destroy of LAG interface, we observed following errors: * mlx5_cmd_check:752:(pid 12556): DESTROY_LAG(0x843) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xe4ac33) * mlx5_cmd_check:752:(pid 12556): DESTROY_LAG(0x843) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xa5aee8).
