They don't.

- address_space_map just returns the value that qemu_ram_ptr_length
returned, and none of its callers deal with NULL (there are dozens)

- likewise for address_space_cache_init

There is also memory_region_get_ram_ptr (which via qemu_map_ram_ptr is
also using xen_map_cache), and none of its callers deal with NULL either.
