Jeff Roberson a67d540832 Use atomics in more cases for object references. We now can completely 
omit the object lock if we are above a certain threshold.  Hold only a
single vnode reference when the vnode object has any ref > 0.  This
allows us to only lock the object and vnode on 0-1 and 1-0 transitions.
