#1678968 — [PATCH] pinctrl: rza1: fix error handling

A compiler warning points out a typo:

drivers/pinctrl/pinctrl-rza1.c: In function 'rza1_pinctrl_probe':
drivers/pinctrl/pinctrl-rza1.c:1260:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This changes the condition to the usual check for failure of the previous
function call.

Fixes: 5a49b644b307 ("pinctrl: Renesas RZ/A1 pin and gpio controller")

Geert already sent a fix for this
