hazptr: Add function to reclaim linked objects without checking hazard pointers.
Summary:
Add unlink_and_reclaim member function to hazptr_obj_base_linked, as an alternative to unlink() that reclaims the object if its link count is zero without checking hazard pointers.
It is useful in destructors of data structures when it is guaranteed that objects are not protected by hazard pointers (e,.g., destructor of ConcurrentHashMap).
