From: Pan Nengyuan <pannengyuan@huawei.com>

collect_image_check() is called twice in img_check(), the filename/format will be alloced without free the original memory.
It is not a big deal since the process will exit anyway, but seems like a clean code and it will remove the warning spotted by asan.
