Christian S.J. Peron 856ebf8530 Make sure the TTY has not disappeared out from under us before calling
ttydevsw_outwakeup().  This should fix panics which occur after remote
login sessions timeout during moderate TTY activity.  An example of
where this might occur is where a pending write to the terminal is
occurring while sshd(8) is shutting down the TTY after a TCP timeout.
