vm: initialize vd->funvec to nil.

* vm.c (vm_make_desc): Initialize vd->funvec to nil so that
when the object is created, it doesn't have a garbage field.
However, there is no risk here that the field will be
traversed by the garbage collector, since immediately after
allocating the objct, we initialize the fields.
