machine: Use host_memory_backend_is_mapped() in machine_consume_memdev()
memory_region_is_mapped() is the wrong check, we actually want to check whether the backend is already marked mapped. For example, memory regions mapped via an alias, such as NVDIMMs, currently don't make memory_region_is_mapped() return "true". As the machine is initialized before any memory devices (and thereby before NVDIMMs are initialized), this isn't a fix but merely a cleanup.
