[PATCH] of: resolver: Add missing of_node_put

[Amitoj Kaur Chawla <amitoj1606-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

for_each_child_of_node performs an of_node_get on each iteration, so
to break out of the loop an of_node_put is required.

Found using Coccinelle. The semantic patch used for this is as follows:

// <smpl>
@@
expression e;
local idexpression n;
@@

 for_each_child_of_node(..., n) {
   ... when != of_node_put(n)
       when != e = n
(
   return n;
|
+  of_node_put(n);
?  return ...;
)
   ...
 }
// </smpl
