[Libvir] [PATCH] Avoid "may be used uninitialized" warning.

[Jim Meyering]

I've been seeing this on rawhide for a few days:

xmconfigtest.c:115: warning: 'old_priv' may be used uninitialized in this function

Here's a fix:

	Avoid "may be used uninitialized" warning.
	* tests/xmconfigtest.c (testCompareParseXML): Initialize "old_priv".
