When domain support was added to regmap-irq it was not possible to remove domains, this was added later by 8ee99ada293b (irqdomain: Support removal of IRQ domains.). We did update the main removal path to free the domain but forgot the error unwinding case during creation that is now in regmap_add_irq_chip_fwnode() after some code motion, meaning that errors during instantiation result in an unused irqchip being left hanging around. Add the missing irq_remove_domain() call where the comment says it should be.
