net: hns3: Fix for hns3 module is loaded multiple times problem
If the hns3 driver has been built into kernel and then loaded with
the same driver which built as KLM, it may trigger an error like
below:
[ 20.009555] hns3: Hisilicon Ethernet Network Driver for Hip08 Family - version
[ 20.016789] hns3: Copyright (c) 2017 Huawei Corporation.

This patch fixes it by adding module version info.
