ARM: meson: Fix refcount leak in meson_smp_prepare_cpus

Browse Source 
[ Upstream commit 34d2cd3fccced12b958b8848e3eff0ee4296764c ]

of_find_compatible_node() 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.
