pinctrl: stm32: return errors from stm32_gpio_direction_output()

In the STMicroelectronics STM32 driver, stm32_gpio_direction_output()
ignores the result of pinctrl_gpio_direction_output() for no good reason.
Let's propagate errors from pinctrl_gpio_direction_output() upstream...

Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.
