The memory device alias needs to be treated as machine ABI as qemu is using it in the migration stream for section labels. To simplify this generate the alias from the slot number unless an existing broken configuration is detected. With this patch the aliases are predictable and even certain configurations which would not be migratable previously are fixed. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1359135
