Fix python pciif script to reference correct 2.0 compatibility variable.

In the Xen 2.0.x compatibility section of xend (where we try to parse
the s-expressions if they came from an SXP configuration file for Xen
2.0.x), the wrong variable is referenced. This fix corrects the python
script to use the correct variable.

Thanks to Mike Wright for reporting this.
