gpiolib: Propagate emulated drive errors when setting arrays
gpiod_set_array_value_complex() ignores errors from the open-drain and
open-source emulation helpers. If a direction change fails,
GPIO_V2_LINE_SET_VALUES_IOCTL still reports success, including when
updating a single line.
Return the first emulation error after freeing the temporary bitmaps.
Keep updates already made to earlier lines and stop processing the
remaining lines, as for errors from gpiochip_set_multiple().
