CVE-2026-98529: gpio: arizona: Fix runtime PM leak in arizona_gpio_direction_out()

In the Linux kernel, the following vulnerability has been resolved:

gpio: arizona: Fix runtime PM leak in arizonagpiodirectionout()

Switching a persistent GPIO line from input to output acquires a runtime PM reference on the parent device, but if the subsequent regmapupdatebits() fails the reference is never dropped and no later directionin() can balance it since the direction was never changed. Drop the reference on the update failure path.
