[PATCH 5.1 222/405] net: hns3: fix keep_alive_timer not stop problem

From: Greg Kroah-Hartman
Date: Thu May 30 2019 - 00:41:22 EST


[ Upstream commit e233516e6a92baeec20aa40fa5b63be6b94f1627 ]

When hclgevf_client_start() fails or VF driver unloaded, there is
nobody to disable keep_alive_timer.

So this patch fixes them.
