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.
