qemu_get_guest_memory_mapping() uses cpu_paging_enabled() to determine
whether to use cpu_get_memory_mapping() to return mappings or whether to
fall back to a simple identity map.

Since by default CPUClass::get_memory_mapping() is not implemented,
change the default to false to use the identity map by default.
