net sched: fix race in mirred device removal
This fixes hang when target device of mirred packet classifier
action is removed.
If a mirror or redirection action is configured to cause packets
to go to another device, the classifier holds a ref count, but was assuming
the adminstrator cleaned up all redirections before removing. The fix
is to add a notifier and cleanup during unregister.
The new list is implicitly protected by RTNL mutex because
it is held during filter add/delete as well as notifier.
