Andreas Rheinhardt 69286f8cf9 avformat/dashdec: Reset pointer to NULL after freeing it 
This is currently safe here, because the effective lifetime of
adaptionset_lang is parse_manifest_adaptationset() (i.e. the pointer
gets overwritten each time on entry to the function and gets freed
before exiting the function), but it is nevertheless safer to reset the
pointer.
