Subject: [PATCH] KVM: fix backport of 3e51570 on hardy
Sasha Levin reported that our backport of 3e51570 ("KVM: Ensure all
vcpus are consistent with in-kernel irqchip settings") has a bug, and
suggested possible fixes. We increment kvm->online_vcpus, but not
decrement it in the case create_vcpu_fd fails, which could cause issues
if it fails and vm is not destroyed after (counter will be out of sync).
In the upstream change this is not a problem since the increment is done
after create_vcpu_fd is called. The solution chosen here is to just
decrement it on the failure path.
