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.
