[RFC PATCH v4 06/30] qapi: make visit_type_size fallback to type_int

[Vasilis Liaskovitis]

Currently visit_type_size checks if the visitor's type_size function pointer is
NULL. If not, it calls it, otherwise it calls v->type_uint64(). But neither of
these pointers are ever set. Fallback to calling v->type_int() in this third
(default) case.
