[media] media: platform: exynos4-is: media-dev: Add missing of_node_put

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

Found using Coccinelle. The simplified version of the semantic patch
that is used for this is as follows:

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

 for_each_available_child_of_node(r,n) {
   ...
(
   of_node_put(n);
|
   e = n
|
+  of_node_put(n);
?  break;
)
   ...
 }
... when != n
// </smpl>
