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.
