media: xilinx: vipp: Fix refcount leak in xvip_graph_dma_init
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
Fixes: df3305156f98 ("[media] v4l: xilinx: Add Xilinx Video IP core")
