Commitad701326b4("avformat/hls: open playlists immediately when AVDISCARD_ALL is dropped") inadvertently caused first_packet to never be cleared, causing select_cur_seq_no() to not use the specific code for live streams. In practice this means that when the user selects a different audio track during live stream (i.e. non-VOD) playback, there may be some additional delay as the code might select an incorrect segment at first, and we have to wait for video to catch audio (if too late segment was selected) or to download more following audio segments (if too early segment was selected). Fix that by restoring the zeroing of first_packet. (cherry picked from commitfd74d45d51)
