This patch (968) changes the way uhci-hcd reports status for
Isochronous URBs.  Until now urb->status has been set to the last
detected error code.  But other HCDs don't do this; they leave the
status set to 0 and report errors only in the individual iso packet
descriptors.  So this patch removes the extra computation and makes
uhci-hcd behave like the others.
