KVM: s390: VCPU_EVENT cleanup for prefix changes
SPX (SET PREFIX) and SIGP (Set prefix) can change the prefix register of a CPU. As sigp set prefix may be handled in user space (KVM_CAP_S390_USER_SIGP), we would not log the changes triggered via SIGP in that case. Let's have just one VCPU_EVENT at the central location that tracks prefix changes.
