pinctrl: sx150x: handle failure case of devm_kstrdup

Browse source

[ Upstream commit a9d9f6b83f ]

devm_kstrdup() may return NULL if internal allocation failed.
Thus using  label, name  is unsafe without checking. Therefor
in the unlikely case of allocation failure, sx150x_probe() simply
returns -ENOMEM.
