Subject: [PATCH] qemu: Fix updating bandwidth limits in live XML

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. Committing this patch
it is now available to update bandwidth 'actual' definition as well,
thus updating domain runtime XML.

(cherry picked from commit f4ba3385ba6b6e9ce6468a48d1cd4637b36696b7)
