USB: avoid the donelist after an error in ohci-hcd

This patch (as972) changes ohci-hcd so that after an error occurs, the
remaining TDs for the URB will be skipped over entirely instead of
going through the donelist.  This enables the driver to give back the
URB as soon as the error is detected, avoiding the need to store the
error status in urb->status.
