Otherwise it'd return a value of unsigned long type regardless of the
type of the arg. I thought it should have same logic as indirect
But it seems not matter since record_entry() would copy it only for
the arg->size. Then type check in __get_arg() might be unnecessary

I've checked it. And it seems to have another problem for indirect
(but not redirect) arrays and strings. Like 'x32 foo'?
