net: octeontx2: Handle XDP_ABORTED and XDP invalid as XDP_DROP

In the current implementation octeontx2 manages XDP_ABORTED and XDP
invalid as XDP_PASS forwarding the skb to the networking stack.
Align the behaviour to other XDP drivers handling XDP_ABORTED and XDP
invalid as XDP_DROP.
Please note this patch has just compile tested.
