[libvirt-glib] Prefer 'for' over 'while'

["Zeeshan Ali (Khattak)" <zeeshanak@xxxxxxxxx>]

From: "Zeeshan Ali (Khattak)" <zeeshanak@xxxxxxxxx>

In this particular case 'for' seems like a more natural choice as then
we don't need to update the iterator (which we were forgetting to do and
causing a hang in Boxes).
