Commit id 'f1f68ca33' added code to remove the directory paths for auto-generated sockets, but that code could be called before the paths were created resulting in generating error messages from virFileDeleteTree indicating that the file doesn't exist. Rather than "enforce" all callers to make the non-NULL and existence checks, modify the virFileDeleteTree API to silently ignore NULL on input and non-existent directory trees.
