Commit 50ebd19e3585 ("pinctrl: samsung: drop pin banks references on
error paths") fixed the pin bank references on the error paths of the
probe function, but there is still an error path where this is not done.

If samsung_pinctrl_get_soc_data() does not fail, the child references
will have acquired, and they will need to be released in the error path
of platform_get_irq_optional(), as it is done in the following error
paths within the probe function.

Replace the direct return in the error path with a goto instruction to
the cleanup function.
