Mateusz Guzik 31977b420a cache: manage negative entry list with a dedicated lock
Since negative entries are managed with a LRU list, a hit requires a
modificaton.

Currently the code tries to upgrade the global lock if needed and is
forced to retry the lookup if it fails.

Provide a dedicated lock for use when the cache is only shared-locked.
