c67x00-sched.c:489:55: warning: Use of memory after it is freed [unix.Malloc]
        usb_hcd_giveback_urb(c67x00_hcd_to_hcd(c67x00), urb, urbp->status);
                                                             ^~~~~~~~~~~~
Problem happens in this block of code

	c67x00_release_urb(c67x00, urb);
	usb_hcd_unlink_urb_from_ep(c67x00_hcd_to_hcd(c67x00), urb);
	spin_unlock(&c67x00->lock);
	usb_hcd_giveback_urb(c67x00_hcd_to_hcd(c67x00), urb, urbp->status);

In the call to c67x00_release_urb has this freeing of urbp

	urbp = urb->hcpriv;
	urb->hcpriv = NULL;
	list_del(&urbp->hep_node);
	kfree(urbp);

And so urbp is freed before usb_hcd_giveback_urb uses it as its 3rd
parameter.

Since all is required is the status, pass the status directly as is
done in c64x00_urb_dequeue
