Use the passed watchdog_device instead of the static global variable when
testing and setting the status in watchdog_ping, watchdog_start, and
watchdog_stop. Note that the callers of these functions are actually
passing the static global variable.

This will be added. We will need this when we go to the sysfs part of the core anyway.
Kind regards,
Wim.
