Exist a null pointer dereference issue in file src/lib/openjp2/dwt.c:2124

Expected behavior and actual behavior.

Hi,
I found a runtime error: applying zero offset to null pointer in current master, and I also reproduced it on latest released version 2.5.0.

Steps to reproduce the problem.

cd openjpeg
mkdir build
cd build

cmake .. -DCMAKE_BUILD_TYPE=Debug
-DCMAKE_C_COMPILER=clang
-DCMAKE_CXX_COMPILER=clang++
-DCMAKE_C_FLAGS="-fsanitize=undefined"
-DCMAKE_CXX_FLAGS="-fsanitize=undefined"

make && make install
opj_decompress -o ./tmp/a.ppm -r 5 -i poc_file
poc_file:
poc_file.zip

Reproduction
root@iZ2vcadn43p7fjzbhl6zqwZ:~#./bin/opj_decompress -o ./tmp/a.ppm -r 5 -i poc_file
