[libvirt] [PATCH 1/2] qemu: Fix updating bandwidth limits in live XML

[Erik Skultety]

When trying to update bandwidth limits on a running domain, limits get
updated in our internal structures, however XML parser reads
bandwidth limits from network 'actual' definition. Commiting this patch
it is now available to update bandwidth 'actual' definition as well,
thus updating domain runtime XML
