[libvirt] [PATCH 2/2] qemu: Relax interface type change check when changing an interface

Then changing some runtime knobs for an interface the qemuDomainChangeNet() is called. This does all kinds of checks to ensure that only supported changes are requested. There is one particular check which purpose is to make sure that interface type does not change. And even if it does, it's a change we can deal with. But since for a running domain any interface with type network becomes interface type bridge, this check fails and an error is reported. What we need to compare are actual types instead of configured ones. Fixes 518026e1595.
