cdnsp_alloc_stream_info() allocates stream context array for stream_info
->stream_ctx_array with cdnsp_alloc_stream_ctx(). When some error occurs,
stream_info->stream_ctx_array is not released, which will lead to a
memory leak.
We can fix it by releasing the stream_info->stream_ctx_array with
cdnsp_free_stream_ctx() on the error path to avoid the potential memory
leak.
