[xml] Small fix for xmlStringGetNodeList()

[Anthony Jones <amj30 hermes cam ac uk>]

Hi,

This should fix a small problem in xmlStringGetNodeList(). The patch is
against libxml-2.4.11 (The problem appears to exist in CVS as well, but I
don't have a proper 'net connection at the moment, so all I've got to go
on is the CVS source browser at cvs.gnome.org). I think the patch is
fairly self explanatory...
