Ard Biesheuvel f00ddc6834 efi: Handle NULL return value when getting loaded image protocol ...

The EFI spec mandates that the handle produced by the LoadImage boot
service has a LoadedImage protocol instance installed on it, but for
robustness, we should still deal with a NULL return value from the
helper routine that obtains this protocol pointer.

If this happens, don't try to start the image but unload it and return
an error.
