Subject: [PATCH] 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.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1000357
(cherry picked from commit f17f164e3acefd590437da84cdcf08c63c7abb0b)
