[PATCH net-next 03/14] net: ethtool: mm: reset verification status when link is down

[Tony Nguyen]

From: Faizal Rahim <faizal.abdul.rahim at linux.intel.com>

When the link partner goes down, "ethtool --show-mm" still displays
"Verification status: SUCCEEDED," reflecting a previous state that is
no longer valid.

Reset the verification status to ensure it reflects the current state.
