rtc: Reduce number of reference frame buffers

In rt, non-svc use case frame buffer allocated for
key frame was not released when a new frame replaced
key frame as the golden reference frame. In this patch,
buffer holding key frame is released when a new golden
frame is encoded, thereby reducing the number of
reference frame buffer requirement by one.
