[PATCH 4.9 08/45] net/ncsi: Use real net-device for response handler

[Greg Kroah-Hartman]

From: John Wang <wangzhiqiang.bj@xxxxxxxxxxxxx>

[ Upstream commit 427c940558560bff2583d07fc119a21094675982 ]

When aggregating ncsi interfaces and dedicated interfaces to bond
interfaces, the ncsi response handler will use the wrong net device to
find ncsi_dev, so that the ncsi interface will not work properly.
Here, we use the original net device to fix it.
