188078467d made clear that resize should
only happen when dealing with a "dynamic" CpuManager. Although this is
very much correct, it causes a regression on Kata Containers (and on any
other consumer of Cloud Hypervisor) in cases where a resize would be
triggered but the vCPUs values wouldn't be changed.
There's no doubt Kata Containers could do better and do not call a
resize in such situations, and that's something that should **also** be
solved there. However, we should also work this around on Cloud
Hypervisor side as it introduces a regression with the current Kata
Containers code.
