This patch fixes a locking bug that can result in deadlock if
the codepath is followed.

From the PR:

  vclean calls vrele leading to deadlock (if usecount > 0)

  vclean() calls vrele() if v_usecount of the node was higher than one.
  But before calling it, it sets the VXLOCK flag, which will make
  vn_lock called from vrele dead-lock.
