[PATCH] Use correct pci addresses during device-detach

[Nitesh_Konkar <nitkon12@xxxxxxxxxxxxxxxxxx>]

From: Nitesh_Konkar <niteshkonkar@xxxxxxxxxx>

The attach-device on live and persistent copies can be done independently.
Thus devices can end up having different pci addresses in live and persistent
copies. The detach device should try to detach the device from their respective
addresses instead of using the same from live/persistent.
