[PATCH] iTCO_wdt: Don't stop on shutdown with nowayout

[Simon Kagstrom]

Currently, the watchdog is turned off when the system shuts down or the
module is unloaded. If nowayout has been selected, this makes no sense
and fails to restart the system if it hangs during reboot, so make it
conditional.

We have a system which has such a hang, and therefore want the watchdog
to be on until the bitter end.
