pinctrl: sirf: add missing put_device() call in sirfsoc_gpio_probe()

A coccicheck run provided information like the following:

drivers/pinctrl/sirf/pinctrl-sirf.c:798:2-8: ERROR: missing put_device;
call of_find_device_by_node on line 792, but without a corresponding
object release within this function.

Generated by: scripts/coccinelle/free/put_device.cocci

Thus add a jump target to fix the exception handling for this
function implementation.
