[ Upstream commit 071d068b89e95d1b078aa6bbcb9d0961b77d6aa1 ]
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: e6b78f2c3e14 ("irqchip: Add the Alpine MSIX interrupt controller")
