fix(gguf): correct mismatched-shape error message
check_quantized_param_shape compares inferred_shape against
current_param_shape, but the error message printed inferred_shape
vs loaded_param_shape — and inferred_shape is derived from
loaded_param_shape, so the reported mismatch was effectively
self-referential and gave no signal about the model's expected shape.
Print current_param_shape (what the model expected) vs inferred_shape
(what the quantized weight decodes to) so the two sides of the
comparison are actually visible.
