Both arguments are not necessarily true. This change is quite like what we
made to hash_search(). There is only one SearchSysCache() which will take an
extra argument "isComplain" (vs. HASH_ENTER_NULL). The error message can be
easily identified from the first parameter "cacheId" -- we will add another
field in struct cachedesc which describs the cache name.
