irqchip: Fix refcount leak in platform_irqchip_probe

irqchip: Fix refcount leak in platform_irqchip_probe

[ Upstream commit 2f4037a073491be6c645b0d4e1fb21b1f69cfc28 ]

of_irq_find_parent() returns a node pointer with refcount incremented,
We should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak.

Fixes: 2af73139b9b4 ("irqchip: Add IRQCHIP_PLATFORM_DRIVER_BEGIN/END and IRQCHIP_MATCH helper macros")
