- Close a race during which the open flag could be cleared but the tun_softc would still be referenced
  by adding a separate TUN_CLOSED flag that is set after tunclose is done referencing it.

- drop the tun_mtx after the flag check to avoid holding it across if_detach which can recurse in to
  if_tun.c
