    NFS - Cleanly unmount NFS on halt/shutdown/reboot
    
    * Abort any in-transit RPCs, disallow new RPCs, and disconnect the
      socket (aka if TCP) when doing a forced NFS unmount.
    
      This fixes left over TCP sockets when doing a normal halt/shutdown/reboot.
    
    * Related user processes will also unblock, but the unmount code will
      still block trying to look up the path and this commit does not quite
      solve that problem.
