qemu: Don't update count of vCPUs if hot-plug fails silently
When cpu hotplug fails without reporting an error, we would fail the command but update the count of vCPUs anyways. Commit 761fc481365703b861429d73a341bde352ba8d41 fixed the case when CPU hot-unplug failed silently, but forgot to fix up the value in this case.

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
