efi: Remove unnecessary (and buggy) .memmap initialization from the Xen EFI driver

So the following commit:

  884f4f66ff ("efi: Remove global 'memmap' EFI memory map")

... triggered the following build warning on x86 64-bit allyesconfig:

drivers/xen/efi.c:290:47: warning: missing braces around initializer [-Wmissing-braces]

It's this initialization in drivers/xen/efi.c:

  static const struct efi efi_xen __initconst = {
  ...
        .memmap                   = NULL, /* Not used under Xen. */
  ...

which was forgotten about, as .memmap now is an embedded struct:

        struct efi_memory_map memmap;

We can remove this initialization - it's an EFI core internal data structure plus
it's not used in the Xen driver anyway.
