ASoC: qcom: audioreach: fix potential null pointer dereference

Browse Source 
commit 8318e04ab2526b155773313b66a1542476ce1106 upstream.

It is possible that the topology parsing function
audioreach_widget_load_module_common() could return NULL or an error
pointer. Add missing NULL check so that we do not dereference it.
