Fixes: 0e6366c2399d ("netdev-offload-dpdk: Implement hw-offload statistics read.")

Signed-off-by: Linda Wang <linda.wang@jaguarmicro.com>

---
 If the device is a vport, the following steps occur:
 1.netdev_offload_dpdk_add_flow()->netdev_offload_dpdk_actions(patterns.physdev)
   ->netdev_offload_dpdk_flow_create()->data->rte_flow_counters[tid]++.
   The incremented of hardware offload counters use physdev in the code.
 2.The decremented of hardware offload counters use netdev.
   In this case, when all the flow tables are deleted, the hw-offload statistics   shows an incorrect value.
