spapr.c: use g_auto* with 'nodename' in CPU DT functions
Next patch will use the 'nodename' string in spapr_core_dt_populate()
after the point it's being freed today.
Instead of moving 'g_free(nodename)' around, let's do a QoL change in
both CPU DT functions where 'nodename' is being freed, and use
g_autofree to avoid the 'g_free()' call altogether.
