avcodec/ac3enc_float, eac3enc: Fix leaks on init error
The AC-3 encoders (both floating- as well as fixed-point) as well as the EAC-3 encoder share code: All use ff_ac3_encode_init() as well as ff_ac3_encode_close(). Until ee726e77 ff_ac3_encode_init() called ff_ac3_encode_close() to clean up on error. Said commit removed this and instead set the FF_CODEC_CAP_INIT_CLEANUP flag; but it did the latter only for the fixed-point AC-3 encoder and not for the other two users of ff_ac3_encode_init(). This caused any already allocated buffer to leak upon a subsequent error for the two other encoders. This commit fixes this by adding the FF_CODEC_CAP_INIT_CLEANUP flag to the other two encoders using ff_ac3_encode_init(). Signed-off-by:Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
