BUG/MEDIUM: map: Fix memory leak in the map converter
The allocated trash chunk is not freed properly and causes a memory leak
exhibited as the growth in the trash pool allocations. Bug was introduced
in commit 271022 (BUG/MINOR: map: fix map_regm with backref).
This should be backported to all branches where the above commit was
backported.
