xhci: Don't print short isoc packets.
Now that the xHCI driver always return a status value of zero for isochronous URBs, when the last TD of an isochronous URB is short, the local variable "status" stays set to -EINPROGRESS. When xHCI driver debugging is turned on, this causes the log file to fill with messages like this: [ 38.859282] xhci_hcd 0000:00:14.0: Giveback URB ffff88013ad47800, len = 1408, expected = 580, status = -115 Don't print out the status of an URB for isochronous URBs.
