soc: amlogic: meson-gx-socinfo: Add of_node_put() before return
The variable np in function meson_gx_socinfo_init takes the return value of of_find_compatible_node, which gets a node but does not put it. If this node is not put it may cause a memory leak. Hence put np after its usefulness has been exhausted. Issue found with Coccinelle.
