sub_reset() was called on cycling subtitle tracks and on seeking. Since we don't want that subtitles disppear on cycling, sd_lavc.c didn't clear its internal subtitle queue on reset, which meant that seeking with PGS subtitles could leave the subtitle on screen (PGS subtitles usually don't have a duration set). Call it only on seeking, so we can also strictly clear the subtitle queue in sd_lavc. (This still can go very wrong if you disable a subtitle, seek, and enable it again - for example, if used with libavformat that uses "SSA" style demuxed ASS subtitle packets. That shouldn't happen with newer libavformat versions, and the user can "correct" it anyway by executing a seek while the subtitle is selected.)
