efi: Accept version 2 of memory attributes table
UEFI v2.10 introduces version 2 of the memory attributes table, which turns the reserved field into a flags field, but is compatible with version 1 in all other respects. So let's not complain about version 2 if we encounter it. Cc: <stable@vger.kernel.org> Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
