net: hns3: Check hdev state when getting link status 

By default, HW link status is up. If hclge_update_link_status is called
before net up, driver will print "link up". It is not suitable. hdev
state check is needed when getting link status.

Fixes: e2cb1dec97 ("net: hns3: Add HNS3 VF HCL(Hardware Compatibility Layer) Support")
