David Hildenbrand f19312d014 s390x/s390-virtio-ccw: don't crash on weird RAM sizes 
KVM is not happy when starting a VM with weird RAM sizes:

  # qemu-system-s390x --enable-kvm --nographic -m 1234K
  qemu-system-s390x: kvm_set_user_memory_region: KVM_SET_USER_MEMORY_REGION
    failed, slot=0, start=0x0, size=0x244000: Invalid argument
  kvm_set_phys_mem: error registering slot: Invalid argument
  Aborted (core dumped)

Let's handle that in a better way by rejecting such weird RAM sizes
right from the start:

  # qemu-system-s390x --enable-kvm --nographic -m 1234K
  qemu-system-s390x: ram size must be multiples of 1 MiB
