fix coredump when secondary process using the hinic port. the
  reason is that during the stage of secondary process port 
initialization, it
  lack the initialization of "eth_dev->dev_ops".

---
v4: adapt to the latest version.
---
v3: update the signed-off information.
---
v2:  solve the coding style issue.
