[libvirt] [PATCH] libvirt-php: fix libvirt_connect and libvirt_version failure without Xen

[Tiziano Mueller]

This is a revised patch to also fix the call to libvirt_version without
arguments and without Xen.

Currently libvirt_connect fails if libvirt has no Xen support.
This is because virGetVersion checks for Xen if typeVer!=NULL.
The same applies for libvirt_version if called without arguments
and no Xen available.
