Upon NETDEV_DOWN event, all xfrm_state objects which are bound to
the device are flushed.
The condition for this is wrong, though, testing dev->hw_features
instead of dev->features. If a device has non-user-modifiable
NETIF_F_HW_ESP, then its xfrm_state objects are not flushed,
causing a crash later on after the device is deleted.
Check dev->features instead of dev->hw_features.
Fixes: d77e38e612a0 ("xfrm: Add an IPsec hardware offloading API")
