watchdog: fix watchdog_set_device() when the default watchdog device is used

If watchdog_set_device() is not called before open_watchdog() then
'watchdog_device' remains 'NULL' while the device is open.

As a result, the "same device" check in watchdog_set_device() does not work
correctly: If no device is specified (e.g. from watchdog_free_device())
then the current fd is not closed.

Fix this by setting 'watchdog_device' to the correct device during
open_watchdog()
