usb-redir: Never return USB_RET_NAK for async handled packets
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.
