mailbox: zynq: add missing of_node_put before return
Fix following coccicheck warning: WARNING: Function "for_each_available_child_of_node" should have of_node_put() before return. Early exits from for_each_available_child_of_node should decrement the node reference counter. Signed-off-by: Wang Qing <wangqing@vivo.com> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
