Zijun Hu 28ca6f1d19 of: Fix refcount leakage for OF node returned by __of_get_dma_parent() ...

commit 5d009e0240 upstream.

__of_get_dma_parent() returns OF device node @args.np, but the node's
refcount is increased twice, by both of_parse_phandle_with_args() and
of_node_get(), so causes refcount leakage for the node.

Fix by directly returning the node got by of_parse_phandle_with_args().
