Add a regression test to check against invalid check_and_init_map_value call inside prealloc_lru_pop. The kptr should not be reset to NULL once we set it after deleting the map element. Hence, we trigger a program that updates the element causing its reuse, and checks whether the unref kptr is reset or not. If it is, prealloc_lru_pop does an incorrect check_and_init_map_value call and the test fails.
