cpufreq: dt: call of_node_put() before error out
If of_match_node() fails, this init function bails out without calling of_node_put(). Also change of_node_put(of_root) to of_node_put(np); both of them hold the same pointer, but it seems better to call of_node_put() against the node returned by of_find_node_by_path().
