[FFmpeg-devel] avformat/hls.c: Fix memory leak

[Valery Kot]

Patch for https://trac.ffmpeg.org/ticket/7610

hls.c:933  free_segment_dynarray(prev_segments, prev_n_segments);
cleans all elements of prev_segments, but does not frees prev_segments
array itself. As a result, process slowly leaks memory every time it
updates playlist.

Added call to av_freep(&prev_segments)
