gpio: omap: Fix gpiochip_add() handling for deferred probe

Currently we gpio-omap breaks if gpiochip_add() returns -EPROBE_DEFER:

[    0.570000] gpiochip_add: GPIOs 0..31 (gpio) failed to register
[    0.570000] omap_gpio 48310000.gpio: Could not register gpio chip -517
...
[    3.670000] omap_gpio 48310000.gpio: Unbalanced pm_runtime_enable!

Let's fix the issue by adding the missing pm_runtime_put() on error.
