Subject: [PATCH 5/5] debugobjects: Delete a piece of redundant code

The statically allocated objects are all located in obj_static_pool[],
no one will use them anymore, the whole memory of obj_static_pool[] will
be reclaimed later. Therefore, there is no need to split the remaining
statically nodes in list obj_pool into isolated ones. Just write
INIT_HLIST_HEAD(&obj_pool) is enough. Since hlist_move_list() directly
discards the old list, even this can be omitted.
