[POWERPC] Add missing of_node_put in drivers/macintosh/therm_adt746x.c

of_node_put is needed before discarding a value received from
of_find_node_by_name, eg in error handling code.

The semantic patch that makes the change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
struct device_node *n;
struct device_node *n1;
statement S;
identifier f;
expression E;
constant C;
@@

n = of_find_node_by_name(...)
...
if (!n) S
... when != of_node_put(n)
    when != n1 = f(n,...)
    when != E = n
    when any
    when strict
(
+ of_node_put(n);
  return -C;

  of_node_put(n);

  n1 = f(n,...)

  E = n

  return ...;
)
