Eric Dumazet 86213f80da net: avoid quadratic behavior in netdev_wait_allrefs_any() 
If the list of devices has N elements, netdev_wait_allrefs_any()
is called N times, and linkwatch_forget_dev() is called N*(N-1)/2 times.

Fix this by calling linkwatch_forget_dev() only once per device.

Fixes: faab39f63c ("net: allow out-of-order netdev unregistration")
