ice: Fix interface being down after reset with link-down-on-close fla…
Browse files Browse the repository at this point in the history
…g on

When performing a reset on ice driver with link-down-on-close flag on
interface would always stay down. Fix this by moving a check of this
flag to ice_stop() that is called only when user wants to bring
interface down.

Fixes: ab4ab73 ("ice: Add ethtool private flag to make forcing link down optional")
