event/octeontx2: fix sub event type

In OCTEONTX2 event device we use sub_event_type to store the ethernet
port identifier when we receive work from OCTEONTX2 ethernet device.
This violates the event device spec as sub_event_type should be 0 in
the initial receive stage.
Set sub_event_type to 0 after copying the port id.
