net/mlx5e: Fail attempt to offload e-switch TC encap flows with vlan on underlay

Browse source

Currently we don't support nor fail attempts to offload encap flows routed
to vlan device on the underlay network. We wrongly consider a vlan underlay
device to be on the same e-switch b/c the switchdev ID is retrieved recursively.

Add explicit check for that and fail such attempts.

Also align to a more strict check for the ingress and the underlay devices
to practically be on the same eswitch.

Fixes: ce99f6b97f ('net/mlx5e: Support SRIOV TC encapsulation offloads for IPv6 tunnels')
Fixes: 3e621b19b0 ('net/mlx5e: Support TC encapsulation offloads with upper devices')
