Subject: [PATCH for-next 7/9] RDMA/hns: Remove unnecessarily calling unregister_inetaddr_notifier function

From: Lijun Ou <oulijun@...wei.com>

When the driver doesn't call register_inetaddr_notifier function, it need
not call unregister_inetaddr_notifier to unregister inet addr. This patch
fixes it.
