[Qemu-devel] [PATCH for 2.1] numa: handle mmaped memory allocation failure correctly

[Igor Mammedov <imammedo@redhat.com>]

when memory_region_init_ram_from_file() fails
memory_region_size() will still return size that was
provided at region init time.
Instead use errp to properly detect error condition.
