net/ncsi: Use real net-device for response handler

stable inclusion
from stable-5.10.7
commit 2cdf8c2747d32c85fbaa6cf36d0971ee43a0a9df
bugzilla: 47429

--------------------------------

[ Upstream commit 427c9405 ]

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.
