Mika Westerberg ef9b7bf52c watchdog: iTCO_wdt: Set NO_REBOOT if the watchdog is not already running
Daniel reported that the commit 1ae3e78c08 ("watchdog: iTCO_wdt: No
need to stop the timer in probe") makes QEMU implementation of the iTCO
watchdog not to trigger reboot anymore when NO_REBOOT flag is initially
cleared using this option (in QEMU command line):

  -global ICH9-LPC.noreboot=false

The problem with the commit is that it left the unconditional setting of
NO_REBOOT that is not cleared anymore when the kernel keeps pinging the
watchdog (as opposed to the previous code that called iTCO_wdt_stop()
that cleared it).

Fix this so that we only set NO_REBOOT if the watchdog was not initially
running.
