[PATCH -next] pinctrl: samsung: Fix return value check in samsung_pinctrl_get_soc_data()

[Wei Yongjun]

From: Wei Yongjun <weiyongjun1 at huawei.com>

In case of error, the function devm_ioremap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should
be replaced with NULL test.

Fixes: 8b1bd11c1f8f ("pinctrl: samsung: Add the support the multiple
IORESOURCE_MEM for one pin-bank")
