Johannes Thumshirn 57337db1b9 watchdog: mena21_wdt: Fix possible NULL pointer dereference 
In a21_wdt_remove() we do a watchdog_unregister_device() on struct
a21_wdt_drv->wdt but never assign it.

Also move the dev_set_drvdata() call in front of the watchdog_register_device()
call, so it doesn't look like an error.
