ice: Fix netif_is_ice() in Safe Mode

[ Upstream commit 8e60dbc ]

netif_is_ice() works by checking the pointer to netdev ops. However, it
only checks for the default ice_netdev_ops, not ice_netdev_safe_mode_ops,
so in Safe Mode it always returns false, which is unintuitive. While it
doesn't look like netif_is_ice() is currently being called anywhere in Safe
Mode, this could change and potentially lead to unexpected behaviour.
