patch to fix use-after-free error in nscd
Coverity flagged a use-after-free error in the nscd cache_read function. It
noticed that find_res->value is getting freed before it gets passed to
memcpy(). It looks like the problem is a missing return (-1) inside the
if (find_res->fifo_policy_item->last_request_time.tv_sec -
find_res->fifo_policy_item->creation_time.tv_sec
common_entry->common_params.max_lifetime.tv_sec) {
block.
