Heinrich Schuchardt a9080e600c efi_loader: avoid buffer overrun in efi_var_restore() ...

The value of buf->length comes from outside U-Boot and may be incorrect.
We must avoid to overrun our internal buffer for excessive values.

If buf->length is shorter than the variable file header, the variable
file is invalid.
