kernel - Fix a rare nfsnode destruction race

* Clear np->n_vnode atomically (w/ the token held) when removing a
  node from the hash table.  The field was previously not being
  cleared at all which could race the nfsnhash lookup code despite
  the vnode interlock and check the lookup code was performing.

* Remove unnecessary tokens around the remaining nfsnode freeing code
  in the reclaim path.
