From: Hans de Goede <hdego...@redhat.com>
USB_RET_NAK is not a valid response for async handled packets (and will
trigger an assert as such).
Also drop the warning when receiving a status of cancelled for packets not
cancelled by qemu itself, this can happen when a device gets unredirected
by the usbredir-host while transfers are pending.
