net/mlx5e: Fix allowed tc redirect merged eswitch offload cases
After changing the parent_id to be the same for both NICs of same
The cited commit wrongly allow offload of tc redirect flows from
VF to uplink and vice versa when devcies are on different eswitch,
these cases aren't supported by HW.
Disallow the above offloads when devcies are on different eswitch
and VF LAG is not configured.
Fixes: f6dc1264f1c0 ("net/mlx5e: Disallow tc redirect offload cases we don't support")
