avfilter/formats: Simplify cleanup for ff_merge_* functions
Now that the output's refs-array is only allocated once, it is NULL in
any error case and therefore needn't be freed at all; Instead an
av_assert1() has been added to guarantee it to be NULL.
Furthermore, it is unnecessary to av_freep(&ptr) when ptr == NULL.
