    kernel - Fix hammer flush-during-reclaim bug
    
    * hammer was improperly using vn_unlock/vn_lock to temporarily unlock a
      vnode.  If this is done during a reclaim vn_lock() will fail, resulting
      in a locking mismatch.
    
    * Use vx_unlock/vx_lock instead, and also check for the reclaim by checking
      the VRECLAIMED flag rather than the VINACTIVE flag.  VINACTIVE might not
      yet be set.
