Bug Description

[Impact]
When the SMMU is enabled, removal of the hns_enet_drv module will trip a WARNING.

[Test Case]
sudo modprobe -r hns_enet_drv

[Fix]
8601a99d7c025 net: hns: Fix WARNING when remove HNS driver with SMMU enabled

[Regression Risk]
Fix is restricted to the hns driver, which is the driver for the nics on the Hi1616 SoC. Regressions would therefore be limited to platforms using this SoC, such as the HiSilicon D05 board.
