Change the return value of function to error value when image size
check correctly passes (io_result == 0), but the image size is zero
(image_size == 0). If such an edge case occurs, the function would
not load any data, but would return successful return code 0.
This edge case is already detected by the current conditional and a
warning is reported, but in this special case, return value 0 was
returned to the caller, which might have confused the caller into
thinking that a valid loading of data occurred, even if it did not.
Handle the edge case, and return error, to assure the caller can not
be confused.
