release VM stack properly.
* cont.c: r55766 change the handling method of Fiber's VM stack.
Resumed Fiber points NULL as VM stack and running Thread has
responsibility to manage it (marking and releasing).
However, thread_start_func_2()@thread.c and thread_free()@vm.c
doesn't free the VM stack if corresponding root Fiber is exist.
This causes memory leak. [Bug #13772]
* cont.c (root_fiber_alloc): fib->cont.saved_thread.ec.stack should be NULL
because running thread has responsibility to manage this stack.
* vm.c (rb_thread_recycle_stack_release): assert given stack is not NULL
(callers should care it).
