Christian Borntraeger 1a0e4c8b02 s390x/kvm: fix small race reboot vs. cmma
Right now we reset all devices before we reset the cmma states.  This
can result in the host kernel discarding guest pages that were
previously in the unused state but already contain a bios or a -kernel
file before the cmma reset has finished.  This race results in random
guest crashes or hangs during very early reboot.
