There is a typo in the subject "efi_laoder".

When a UEFI payload just returns instead of calling the Exit() callback, we handle that in efi_do_enter() and call Exit on its behalf, so that the loaded_image->exit_status value is correct.

We were missing that logic in StartImage(). Call it there too.
