avformat/hlsenc: Fix memleak when deleting old segments

Browse Source 
if the directory name of the segments contains "%v".

This memleak is caused by masking the pointer that will eventually
be freed by a variable of the same name in a smaller scope.
Therefore the pointer that gets freed is always NULL when it is
freed and the allocated data leaks.
