ARM: meson: Fix refcount leak in meson_smp_prepare_cpus
[ 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.
Fixes: d850f3e5d296 ("ARM: meson: Add SMP bringup code for Meson8 and Meson8b")
