[PATCH net-next V2] net: hns3: remove unnecessary pci_set_drvdata() and devm_kfree()

[Wei Yongjun <weiyongjun1@huawei.com>]

There is no need for explicit calls of devm_kfree(), as the allocated
memory will be freed during driver's detach.

The driver core clears the driver data to NULL after device_release.
Thus, it is not needed to manually clear the device driver data to NULL.

So remove the unnecessary pci_set_drvdata() and devm_kfree().
