locking/spinlocks, s390: Implement vcpu_is_preempted(cpu)

This implements the s390 version for vcpu_is_preempted(cpu),
by reworking the existing smp_vcpu_scheduled() function into
arch_vcpu_is_preempted().

We can then also get rid of the local cpu_is_preempted()
function by moving the CIF_ENABLED_WAIT test into
arch_vcpu_is_preempted().
