efi_loader: centralize messaging for efi_init_obj_list

Browse Source 
If efi_init_obj_list() fails we cannot use the UEFI sub-system.

* Instead of having messages for this everywhere write an error message
  in efi_init_obj_list().
* Always use (ret != EFI_SUCCESS) when checking the return value of
  efi_init_obj_list().
* Remove the return code from the error message as it does not help
  users to understand which initialization went wrong.
