pinctrl: nuvoton: check for devm_kasprintf() failure

Browse source

[ Upstream commit 4be1eaf322 ]

devm_kasprintf() may return NULL on failure of internal allocation thus
the assignment to  .label  is not safe if not checked. On error
npcm7xx_gpio_of() returns negative values so -ENOMEM in the
(unlikely) failure case of devm_kasprintf() should be fine here.
