This should happen no matter what value status is, so long as it's
non-zero. And by the same reasoning: The URB has already been linked,
the HCD was unable to accept it, so it must be sent to giveback and
submit_urb must return 0.
We can still use -ENOMSG for this unusual case, but it won't matter since
the value won't get sent back to the submitter.
