[PATCH] sparc32,leon: Fix reference leak in leon_ipi_init

[Miaoqian Lin]

of_find_node_by_path() returns a node pointer with
refcount incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Fixes: 1ca0c808c60f ("sparc32,leon: Implemented SMP IPIs for LEON CPU")
