 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.

Patch added to usb patch queue (2+3 from v1 too).

[Qemu-devel] [PATCH] 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).
