configfs: call fsnotify_rmdir() hook
This will allow generating fsnotify delete events on unregister of group/subsystem after the fsnotify_nameremove() hook is removed from d_delete(). The rest of the d_delete() calls from this filesystem are either called recursively from within debugfs_unregister_{group,subsystem}, called from a vfs function that already has delete hooks or are called from shutdown/cleanup code.
