[libvirt] [PATCH v3 4/6] qemuhotplug: Use a more generic function to update devices

[Tomasz Flendrich]

Previously, specific functions had to be used to test updating devices,
different for every device type. It was too much trouble and noone
bothered with it.
qemuDomainUpdateDeviceLiveAndConfig is now being used instead.
