(except if we want to do the same in batch for multiple VCPUs - but that's a micro optimization) So let's simply perform the exit_sie() calls directly when setting the other magic block bits in the SIE. Otherwise e.g. kvm_s390_set_tod_low() still has other VCPUs running after that call, working with a wrong epoch.
