[PATCH 1/2] memory: tegra: delete unneeded of_node_put

[Julia Lawall <Julia.Lawall@lip6.fr>]

for_each_child_of_node performs an of_node_put on each iteration, so
putting an of_node_put before a continue results in a double put.

The semantic match that finds this problem is as follows
(http://coccinelle.lip6.fr):

// <smpl>
@@
expression root,e;
local idexpression child;
iterator name for_each_child_of_node;
@@

 for_each_child_of_node(root, child) {
   ... when != of_node_get(child)
*  of_node_put(child);
   ...
*  continue;
}
// </smpl>
