memory hotplug: memmap_init_zone called twice
__add_zone calls memmap_init_zone twice if memory gets attached to an empty zone. Once via init_currently_empty_zone and once explictly right after that call. Looks like this is currently not a bug, however the call is superfluous and might lead to subtle bugs if memmap_init_zone gets changed. So make sure it is called only once.
