[PATCH] efi_loader: change the error message when storing EFI variables

[Ilias Apalodimas]

When we try to store EFI variables on a file, we need to use an ESP.
if an ESP is not found, variables will change in memory, but U-Boot
won't be able to restore them across reboots.

Adjust the error message so users can understand what's going on
