ASoc: audio-graph-card2: Fix refcount leak bug in __graph_get_type()

Browse source

[ Upstream commit eda26893da ]

We should call of_node_put() for the reference before its replacement
as it returned by of_get_parent() which has increased the refcount.
Besides, we should also call of_node_put() before return.
