Matt Spinler 31c765081d watchdog: stop watchdog first on startup 
Some watchdog implementations may do things other than issue
a reboot on a watchdog timeout.  In this case, there's the
possibility of restarting this program from the state of
the watchdog device not being properly stopped (done by writing
a 'V' and closing the device).  Since it wasn't stopped, the
driver may not be able to restart the watchdog when this program
reopens it and starts pinging it.

To fix this, the code will always first issue the stop when it
starts up.
