Currently, vcpu can be destructed only when kvm instance destroyed.
Change this to vcpu's destruction before kvm instance, so vcpu MUST
and CAN be destroyed before kvm's destroy.

Oops, that's only needed when the unplug API is introduced.

I think it is OK to to add such an API later on, but I really want
the author to write the plan in the changelog.

Otherwise people not belonging to Red Hat or IBM cannot know what
this commit is aiming at.

I am not objecting to this patch itself, but the way this kind of change
is being introduced seems not be in a good manner.
