s390/kvm: fix diag318 propagation and reset functionality
The Control Program Name Code (CPNC) portion of the diag318 info must be set within the SIE block of each VCPU in the configuration. The handler will iterate through each VCPU and dirty the diag318_info reg to be synced with KVM on a subsequent sync_regs call. Additionally, the diag318 info resets must be handled via userspace. As such, QEMU will reset this value for each VCPU during a modified clear, load normal, and load clear reset event.
