[PATCH] bus: arm-cci: Add of_node_put() before break

[Nishka Dasgupta]

Each iteration of for_each_child_of_node puts the previous node, but
in the case of a break from the middle of the loop, there is no put,
thus causing a memory leak. Add an of_node_put before the break.
Issue found with Coccinelle.
