irqchip/renesas-rzg2l: Fix error path in rzg2l_irqc_common_probe()

Replace pm_runtime_put() with pm_runtime_put_sync() when
irq_domain_create_hierarchy() fails to ensure the device suspends
synchronously before devres cleanup disables runtime PM via
pm_runtime_disable().

[ tglx: Fix up subject and change log to be precise ]
