Commit fe014d4e6b55 (staging: wilc1000: free memory allocated for general info message from firmware) introduced bug by using wrong source address in kmemdup(). 'conn_info.req_ies' is used for source address in kempdup() instead of 'hif_drv->usr_conn_req.ies'.
This commit fixes the NULL pointer dereference issue in host_int_parse_assoc_resp_info() by using the correct source address in kmemdup().
