Thomas Prescher d46517559b vmm: don't allow resizing to 0 vCPUs ...

No sane guest OS will allow hotplugging all cpus.
However, the REST API currently allows specifying
`ch-remote resize --cpus 0`.

On Linux, we can then observe the following error in the kernel log:

processor cpu0: Offline failed.

Subsequent resize commands via ch-remote will then fail with
VcpuPendingRemovedVcpu because the removal of cpu0 was never
successful.

Fix this by disallowing resizing to zero vCPUs.
