update: always look up parent directory in updatePath()

Browse Source 
By always creating the parent directory, we can use delete_name_in()
without further lookups.  The parents which may non exist will be
pruned later.  An update request for a non-existing or empty directory
should be quite unusual, so this doesn't add any measurable overhead.
