Log:
SVN rev 186483 on 2008-12-25 02:14:25Z by kmacy
- 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
