This basically reverts cc0380222add8df8ff9b3bd95eaf2b9d8c4c0d11. At the time of said commit, cleanup on init failure was very buggy. For codecs with the INIT_CLEANUP cap, the close function could be called on error even before the private data has been allocated; and when using frame threading the same could also happen even without said flag. Some mpegvideo decoders were affected by the latter. Yet both of these issues have been fixed long ago, the latter in commit e9b66175793e5c2af19beefe8e143f6e4901b5df. Therefore the workaround in ff_mpv_common_end() can be removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
