Ilan Tayari 2c1497bbc8 xfrm: Fix NETDEV_DOWN with IPSec offload 
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.
