Subject: [PATCH iwl-net 2/2] ice: Shut down VSI with "link-down-on-close" enabled

From: Ngai-Mint Kwan <ngai-mint.kwan@...el.com>

Disabling netdev with ethtool private flag "link-down-on-close" enabled
can cause NULL pointer dereference bug. Shut down VSI regardless of
"link-down-on-close" state.

Fixes: 8ac7132704f3 ("ice: Fix interface being down after reset with link-down-on-close flag on")
