watchdog: Fix NULL pointer dereference when releasing cdev
watchdog_hrtimer_pretimeout_stop needs the watchdog device to have a
valid pointer to the watchdog core data to stop the pretimeout hrtimer.
Therefore it needs to be called before the pointers are cleared in
watchdog_cdev_unregister.
Fixes: 7b7d2fdc8c3e ("watchdog: Add hrtimer-based pretimeout feature")
