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.
