From: Chen Hanxiao <chenhanxiao@xxxxxxxxx>
We used VIR_ERR_OPERATION_FAILED when target detaching device
is not found.
That error code VIR_ERR_OPERATION_FAILED is widely used,
so the tools powered by libvirt, such as nova,
can't catch the exact errors from libvirt.
This patch uses VIR_ERR_NO_DEVICE instead.
