Upon writing to "remove" file, debugfs_remove_recursive() blocks while
holding rtnl_lock. This is because debugfs' file_ops callbacks are
executed in debugfs_use_file_*() context which prevents file removal.
Fix this by only flagging the device for removal and then do the cleanup
in file_ops.release callback which is executed out of that context.

Since v3.11, netdevice notification data are of type
"struct netdev_notifier_info". Handle it as such!
This should fix a critical bug in which devices are unable get released
because trelay does not release resources in response to UNREGISTER
event spamming the log with something like:
unregister_netdevice: waiting for eth0.1 to become free. Usage count = 1

kernel module packages directly.
