gpio: arizona: Fix runtime PM leak in arizona_gpio_direction_out()
Switching a persistent GPIO line from input to output acquires a
runtime PM reference on the parent device, but if the subsequent
regmap_update_bits() fails the reference is never dropped and no later
direction_in() can balance it since the direction was never changed.
Drop the reference on the update failure path.
