irqchip/irq-mvebu-gicp: Fix refcount leak in mvebu_gicp_probe

Browse Source 
[ Upstream commit 9419e700021a393f67be36abd0c4f3acc6139041 ]

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.
