watchdog: s3c2410_wdt: Simplify using dev_err_probe()
Make use of dev_err_probe() also for error paths that don't have to handle -EPROBE_DEFER. While the code handing -EPROBE_DEFER isn't used for these error paths, it still simpler as it cares for pretty printing the error code and usually needs one code line less as it combines message emitting and error returning. This also unifies the format of the error messages.
