driver: Prevent disabling when there are offlined CPUs

If Linux has some of the CPUs offlined itself, i.e. not for passing them
to other cells, and we disable the hypervisor then, those CPUs will not
be released. Attempts to online them again later on will fail. Reject
disable requests in such a case.
