ffmpeg | branch: master | Gautam Ramakrishnan <gautamramk at gmail.com> | Fri Aug 28 00:33:36 2020 +0530| [341064d68a134e2fb3dd35f8f5b50c6df8506c10] | committer: Michael Niedermayer

libavcodec/jpeg2000: fix tag tree reset

The implementation of the tag tree did not
set the correct reset value for the encoder.
This lead to inefficent tag tree being encoded.
This patch fixes the implementation of the
ff_tag_tree_zero() function.
