[PATCH v4 2/4] watchdog: rzn1: Use dev_err_probe()

[Wolfram Sang <wsa+renesas@sang-engineering.com>]

From: "Herve Codina (Schneider Electric)" <herve.codina@bootlin.com>

In the probe() function the following pattern is present several times:
	if (err) {
		dev_err(dev, ...);
		return err;
	}

Replace them by dev_err_probe() calls.
