Subject: [PATCH] KVM: s390: implement KVM_REQ_TLB_FLUSH and make use of it

Use the KVM_REQ_TLB_FLUSH request in order to trigger tlb flushes instead
of manipulating the SIE control block whenever we need it. Also trigger it for
a control register sync directly instead of (ab)using kvm_s390_set_prefix().
