Re: [RFC v2 19/20] efi_loader: disk: not create BLK device for BLK(IF_TYPE_EFI) devices

When we create an efi_disk device with an UEFI application using driver binding protocol, the 'efi_driver' framework tries to create a corresponding block device(UCLASS_BLK/IF_TYPE_EFI). This will lead to calling a PROBE callback, efi_disk_probe(). In this case, however, we don't need to create another "efi_disk" device as we already have this device instance.

So we should avoid recursively invoke further processing in the callback function.
