  Log:
  Don't acquire an additional vnode reference to a vnode when it is opened
  and then release it when it is closed: we rely on the caller to keep the
  vnode around with a valid reference.  This avoids vrele() destroying the
  vnode vop_close() is being called from during a call to vop_close(), and
  a crash due to lockmgr recursing the vnode lock when a Coda unmount
  occurs.
