ice: Shut down VSI with "link-down-on-close" enabled 

[ Upstream commit 6d05ff55ef4f4954d28551236239f297bd52ea48 ]

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: 8ac7132704 ("ice: Fix interface being down after reset with link-down-on-close flag on")
