USB: add urb->unlinked field
This patch (as970) adds a new urb->unlinked field, which is used to store the status of unlinked URBs since we can't use urb->status for that purpose any more. To help simplify the HCDs, usbcore will check urb->unlinked before calling the completion handler; if the value is set it will automatically override the status reported by the HCD.
