ASoC: qdsp6: fix potential memory leak in q6apm_get_audioreach_graph()

Browse Source 
q6apm_get_audioreach_graph() allocates a memory chunk for graph->graph
with audioreach_alloc_graph_pkt(). When idr_alloc() fails, graph->graph
is not released, which will lead to a memory leak.

We can release the graph->graph with kfree() when idr_alloc() fails to
fix the memory leak.
