The image is not unloaded if a security violation occurs.
If efi_set_load_options() fails, we do not free the memory allocated for
the optional data. We do not unload the image.
* Unload the image if a security violation occurs.
* Free load_options if efi_set_load_options() fails.
* Unload the image if efi_set_load_options() fails.
Fixes: 53f6a5aa86 ("efi_loader: Replace config option for initrd loading")
