[libvirt] Committed a fix for building with -Werror

[Chris Lalancette]

I just committed this:

+Thu Oct 16 15:41:00 CEST 2008 Chris Lalancette <clalance at redhat.com>
+       * Compiling with -Werror showed a possible use before initialization
+       in src/qemu_driver.c.  Make sure to initialize the olddisk ptr to
+       NULL.
