powerpc/spufs: Fix refcount leak in spufs_init_isolated_loader
[ Upstream commit 6ac059dacffa8ab2f7798f20e4bd3333890c541c ]
of_find_node_by_path() returns remote device nodepointer with
refcount incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
