s390x/sclp: fix missing be conversion
Linux crashes right now if maxmem > mem is specified on the command line. On s390x, the guest can hotplug memory itself right now - very weird - and e.g. Fedora 27 will simply add all memory it can when booting. So now, we have at least the same behavior on TCG and KVM.
