Change subject: Free not only first entry Currently lru_reap_impl only check whether first
entry of lq->q can be reclaimable. But sometimes, the first entry can not be reclaimed
for a long time, then we have to malloc several million new mdcache_entry_t. The size of
mdcache_entry_t is 1200 bytes, then the memory of mdcache_entry_t is serveral GB, which
should be improved. So we check all the entries of lq_q, whether can be reclaimed, to
avoid malloc so many mdcache_entry_t.
