KVM: s390: remove __cpu_is_stopped and expose is_vcpu_stopped
The function "__cpu_is_stopped" is not used any more. Let's remove it and
expose the function "is_vcpu_stopped" instead, which is actually what we want.
This patch also converts an open coded check for CPUSTAT_STOPPED to
is_vcpu_stopped().
