In flush_sit_entries::add_discard_addrs path, cur_map and ckpt_map
are the same, but in exist_trim_candidates::add_discard_addrs,
cur_map is updated one, and newer than ckpt_map, so we need to use
cur_map to check whether there are discard candidates.
Advertising
v1->v2: one problem of check discard candidates reported by Chao,
besides, update commit message.
