If an irq_domain is auto-recursive and irq_domain_alloc_irqs_recursive() for its parent has returned an error, then do return and avoid calling irq_domain_free_irqs_recursive() uselessly, because: - if domain->ops->alloc() had failed for an auto-recursive irq_domain, then irq_domain_free_irqs_recursive() had already been called; - if domain->ops->alloc() had failed for a not auto-recursive irq_domain, then there is nothing to free at all.
