dmaengine: xilinx_dma: call of_node_put() when breaking out of for_each_child_of_node()

Browse Source 
[ Upstream commit 596b53ccc36a546ab28e8897315c5b4d1d5a0200 ]

Since for_each_child_of_node() will increase the refcount of node, we need
to call of_node_put() manually when breaking out of the iteration.
