s390x/kvm: proper use of the cpu states OPERATING and STOPPED
This patch makes sure that halting a cpu and stopping a cpu are two different things. Stopping a cpu will also set the cpu halted - this is needed for common infrastructure to work (note that the stop and stopped flag cannot be used for our purpose because they are already used by other mechanisms). A cpu can be halted ("waiting") when it is operating. If interrupts are disabled, this is called a "disabled wait", as it can't be woken up anymore. A stopped cpu is treated like a "disabled wait" cpu, but in order to prepare for a proper cpu state synchronization with the kvm part, we need to track the real logical state of a cpu.
