conf: fix a failure when detaching a usb device
#virsh detach-device $guest usb.xml
error: Failed to detach device from usb2.xml
error: operation failed: host usb device vendor=0x0951 \
product=0x1625 not found
This regresstion is due to a typo in matching function. The first
argument is always the usb device that we are checking for. If the
usb xml file provided by user contains bus and device info, we try
to search it by them, otherwise, we use vendor and product info.
The bug occurred only when detaching a usb device with no bus and
device info provided in the usb xml file.
