Subject: [PATCH] Minor refactor: use erts_cleanup_offheap_list in
 erl_db_util.c

There are multiple places in erl_db_util.c where a temporary ErlOffHeap
is created just to call erts_cleanup_offheap(). This function then
extracts the first field, and passes it to erts_cleanup_offheap_list().
Calling that function directly is simpler and removes the need to create
the temporary object.
