From: Hans de Goede <hdego...@redhat.com>
The usbredir protocol uses a status of usb_redir_stall to indicate that
an iso data stream has stopped (ie because the urbs failed on resubmit),
but iso packets should never return a result of USB_RET_STALL, since iso
endpoints cannot stall. So instead simply always return USB_RET_NAK on
iso stream errors.
