watchdog: timeRemaining doesn't need to check enabled

The Timer is fully owned by the Watchdog and is only enabled when the
watchdog is enabled. Therefore, we only need to check the state of the
timer instead of the interface and timer before populating the
timeRemaining value. This simplifies later patches and does not make any
functional change.
