patch 9.2.0801: Memory leak in f_getreginfo() on alloc failure

patch 9.2.0801: Memory leak in f_getreginfo() on alloc failure

Problem: Memory leak in f_getreginfo() on alloc failure
Solution: Call list_unref() with list var (Yasuhiro Matsumoto).

Since dict_add_list() leaves ownership with the caller on failure, the
freshly built list must be freed when the add fails.
