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: faab39f63c1f ("net: allow out-of-order netdev unregistration")
