gpio: davinci: fix IRQ domain leak on devm_kzalloc failure

In davinci_gpio_irq_setup(), after successfully creating an IRQ domain
with irq_domain_create_legacy(), a subsequent devm_kzalloc() failure
in the bank loop causes the function to return -ENOMEM without
removing the IRQ domain.

Unlike devm-managed resources, irq_domain_create_legacy() does not
auto-clean up on probe failure, so the domain is leaked.

Fix by calling irq_domain_remove() before returning on allocation
failure.
